How Republicans Re-engineered the Tax Code in America


“The product of years of Republican effort, the American tax code now blends traditional supply-side economics with President Trump’s populist 2024 campaign promises.

 

When Republicans last set out to change taxation in America, they spent years combing through the details of the internal revenue code. They traveled the country, held hearings and drafted early versions of a bill, eventually passed in 2017, that they hoped would transform a sclerotic tax system with long-held conservative principles.

 

This time around, as Republicans prepared for another opportunity to change how taxes in the world’s largest economy are collected, their core ideas came not from a Washington think tank or corporate accountant. Instead, in President Trump’s telling, a waitress at his hotel in Las Vegas complained to him about having to pay taxes on her tips while he dined there during the 2024 campaign.

 

Soon, the seemingly offhand remark became a centerpiece of Mr. Trump’s successful campaign back into office. Republicans on Capitol Hill embraced the idea, too, and Congress this week voted to create a new tax exemption for tipped income for the next few years. At an event at the White House last month promoting the legislation, Mr. Trump credited the waitress with helping him win Nevada, where many people work for tips.

 

“A legend was made,” Mr. Trump said. “We won Nevada by so much. Republicans don’t win Nevada. We won Nevada. So I want to thank that young, beautiful waitress. Thank you very much.”

 

The tips provision, while ultimately only a sliver of the sprawling package that lawmakers passed this week, marked an important evolution in how the Republican Party, long dedicated to lowering taxes, has approached that goal. Rather than the type of systematic re-examination of the tax code that took place in 2017, the new Republican bill introduces a series of novel, populist and temporary cuts that Mr. Trump cooked up during the 2024 campaign to try to win the support of key constituencies.

 

At the same time, even as Mr. Trump’s return to office pointed the party’s tax agenda in a more populist direction, the new bill is in many ways the apotheosis of a traditionally conservative, supply-side philosophy. Once Mr. Trump signs the legislation, which he is expected to do on Friday, many of the tax cuts made in 2017 will be the law of the land for the foreseeable future, rather than just temporary features.

 

Overall, the tax code now blends this classical Republican vision of a more corporate-friendly and simpler tax code with Mr. Trump’s improvisational notions for popular, easy-to-brand tax cuts. Those two strands have combined, in a sometimes contradictory way, to create a tax system that is expected to bring in far less government revenue than many experts believe is necessary, all while generating little additional economic growth and still returning the largest savings to the rich.

 

To satisfy the demands of hard-right lawmakers who wanted to limit the increase in the deficit, the legislation also slashes the social safety net, with changes that are expected to cause millions of Americans to lose health insurance and food benefits.

 

To conservative tax experts and some former Republican aides, this new orthodoxy in the G.O.P. is an incoherent one, a reflection of a political party that clings to much of its traditional economic agenda while only partially shifting toward trying to offer more tangible benefits to the working class, increasingly the Republican base of support.

 

“There doesn’t seem to be an overarching theory of the case of what the tax code ought to be doing, and that’s a real missed opportunity,” said Jonathan Burks, who was chief of staff to former Speaker Paul D. Ryan, a Wisconsin Republican. “You’ve not had that same intellectual trend, in terms of developing a policy agenda over the last eight years of what ‘good’ looks like, and instead you have a handful of campaign promises that have become these defining requirements.”

 

‘It Was Time’

 

When Dave Camp, a former Republican congressman from Michigan, led the powerful Ways and Means Committee from 2011 to 2015, there were clear problems with the tax code. Both Republicans and Democrats wanted to rework the taxation of large companies’ earnings overseas and believed that the corporate tax rate, then at 35 percent, was too high. They worried that the system left American companies at a competitive disadvantage.

 

“I knew it was time that there was a serious reform of our tax code,” said Mr. Camp, now a senior policy adviser at the accounting and consulting firm PricewaterhouseCoopers. “It did take years to really get the issues in a place where policy could happen.”

 

That left the G.O.P. well prepared when, to much of the world’s surprise, Mr. Trump won the 2016 election and the party swept to full control in Washington. The pent-up desire to fundamentally change how American companies were taxed then merged with a Republican instinct to always cut taxes for individuals when given the chance.

 

“There is a general feeling among Republicans that taxes are always too high,” said Dave Kautter, a top tax policy official in the first Trump administration. “So we had to get individual taxes down, but the big problem was business taxes. We were becoming uncompetitive as an economy on the world stage.”

 

A first principle for Republicans at the time was to “broaden the base and lower the rates,” a mantra for conservative tax experts. Essentially, the goal was to excise as many loopholes and special deductions from the tax code as possible, increasing the amount of income subject to taxation. That larger pool of money could then be taxed at lower rates, limiting the revenue loss.

 

This approach meant that Republicans sought to crack down on deductions that, while affecting only relatively small slices of the population, could be very valuable for those who took them. Chief among them was the state and local tax deduction, which allows Americans to write off taxes they have paid to their state and local governments on their federal return — the so-called SALT deduction.

 

With the 2017 bill, called the Tax Cuts and Jobs Act, Republicans capped SALT at $10,000, enraging lawmakers from high-tax states like New York and New Jersey who voted against the bill. The new cap prompted a yearslong crusade to restore a larger deduction.

 

At the same time, the 2017 law limited other valued tax breaks, like one for mortgage interest, while expanding the standard deduction, which is available to Americans who choose not to itemize, or claim specific tax breaks. The result was that many more Americans chose to take the standard deduction; in 2017, before the law passed, 69 percent of Americans did so, but by 2020, the share was up to 91 percent of Americans.

 

Throughout the process of crafting the 2017 bill, Mr. Trump had relatively few demands, pushing for the corporate rate to go as low as 20 percent. Republicans were ultimately able to cut it to 21 percent in the bill, still a huge drop from 35 percent, and at the same time offer new tax incentives for capital investment and overhaul the entire international tax system.

 

“His big demands were much more top-line like that and not all this laundry list of priorities that he has today,” said George Callas, a former Republican tax aide.

 

Overall, the bill was the most thorough tax overhaul in a generation. It slashed rates for corporations, as well as for individuals up and down the income ladder. It was expensive and gave its biggest benefits to the rich. And it cleaned up the tax code by curbing some key deductions. Because of its cost, Republicans decided to schedule many of the tax cuts to expire at the end of 2025 so that the sticker price seemed lower.

 

‘We Have to Do Something’

 

Setting a 2025 expiration helped Republicans record a smaller cost of the bill in 2017 — estimates at the time put it at $1.5 trillion. But it created another conundrum for Republicans. They would have to eventually figure out how to keep the cuts going, or risk suddenly higher taxes for many Americans in 2026, a potential political disaster ahead of the midterm elections.

 

“The problem now is there was no big motivation for another tax reform,” said Erica York, an analyst at the Tax Foundation, a think tank that generally favors lower taxes. “It’s: ‘We have this big expiration, and we have to do something.’”

 

Into that void came Mr. Trump’s 2024 re-election campaign. Not only did he run on making the 2017 tax cuts permanent, but he also unleashed a barrage of ideas for new tax cuts, often targeted toward whatever audience he was speaking in front of. At a campaign rally on Long Island, Mr. Trump went so far as to call for lifting the cap on the state and local deduction that he had signed into law.

 

Versions of many of those proposals — including lifting the SALT cap, making car loans tax-deductible and not taxing overtime — are soon to become law, while several other campaign promises, like changing how Americans living overseas are taxed, were abandoned once Mr. Trump took office.

 

With Republicans in Congress largely focused on extending the 2017 tax cuts, Mr. Trump’s off-the-cuff and outside-the-box ideas were an opportunity for the party to offer new tax cuts. The hope was that the cuts, many of them aimed at working-class Americans, could help blunt Democratic attacks that Republicans cut taxes only for the rich.

 

Still, the effect of the many new tax breaks in the legislation passed this week is to reverse much of the progress made toward simplifying the tax system. More Americans are likely to itemize because of the new, $40,000 cap on the state and local tax deduction, while many workers and employers will have to figure out how to claim the new deductions for tipped and overtime income. And even if they take the standard deduction, many Americans will now be able to write off up to $1,000 ($2,000 for married couples) in charitable donations from their taxes.

 

“When the new provision is a tax break, people are happy to have some compliance costs to get the tax break,” said Joel Slemrod, an economist at the University of Michigan. “But from the point of view of the tax system, we end up with more complexity. That’s how it happens.”

 

And the populist nature of the new tax cuts is limited. Several of them will be available only to the slices of the working class that happen to work for tips or overtime, though a new $6,000 deduction will be available for many Americans 65 and over. But working-class gains from the tax cuts are expected to be overwhelmed by the loss of benefits from the bills’ cuts to the social safety net.

 

To offset part of the cost of the cuts, Republicans sliced deeply into Medicaid and food stamps, rather than raising taxes on rich Americans, an option that some populist-minded conservatives like the former Trump adviser Stephen K. Bannon pushed for and that Mr. Trump repeatedly flirted with. The vast majority of the tax cuts in the legislation are simply extending the last round of cuts from 2017.

 

“We see in this bill there has been a shift in the way Republicans do tax policy, but it’s not a massive shift,” Ms. York said. “The corporate rate is being maintained, the top rate is being maintained, there aren’t tax increases on capital gains. There’s been a shift to include these more populist policies Trump campaigned on, but not go so far as to raise taxes on the rich or anything like that.”” [1]

 

2017 tax cuts stimulated the American economy and are a big reason Trump has been re-elected.

 

The assertion that the 2017 tax cuts stimulated the American economy and were a major factor in Donald Trump's potential re-election is a complex claim with various perspectives and conflicting evidence

.

Arguments for the 2017 Tax Cuts (Tax Cuts and Jobs Act - TCJA) Stimulating the Economy:

 

    Proponents' claims: During the debate surrounding the TCJA, proponents, including the Trump administration, claimed the tax cuts would significantly boost economic growth and benefit American workers.

    Specific provisions: The TCJA reduced the corporate tax rate, provided tax breaks to pass-through businesses, lowered individual income tax rates, increased the standard deduction, and made changes to international taxation. These changes were intended to incentivize investment and work, leading to economic growth.

    Early GDP growth: Some point to the increase in GDP growth in 2018 as evidence of the TCJA's positive impact.

    Increased investment: Research suggests the TCJA may have increased corporate investment in equipment and structures.

    Potential longer-term effects: Reductions in individual income tax rates could potentially encourage more work and saving, leading to longer-term economic effects.

 

Arguments against the 2017 Tax Cuts Stimulating the Economy Significantly:

 

    Disproportionate benefits to the wealthy: Analyses consistently show that the majority of the benefits from the TCJA accrued to higher-income households and corporations. The Tax Policy Center estimated that the top 1% would receive an average tax cut of over $60,000 in 2025, compared to less than $500 for the bottom 60%.

    Limited impact on overall economic growth: Rigorous research has found little evidence of a significant impact on overall GDP growth, investment, or wages.

    Failed promises: Claims that the TCJA would lead to substantial boosts in household income for average workers or that it would "pay for itself" have not been borne out by the data.

    Increased national debt: The TCJA is projected to significantly increase the national debt, with estimates ranging from $1.9 trillion to $4.6 trillion over ten years.

    Potential long-term negative effects: A Congressional Budget Office analysis suggests that extending the TCJA could shrink the economy in the long run due to rising deficits and higher interest rates.

 

Regarding the Impact on Trump's Re-election Chances:

 

    Political considerations: The TCJA's temporary individual tax cuts were set to expire at the end of 2025, creating a potential "tax cliff" that could have become a political issue in future elections.

    Republican efforts to extend: Republicans have actively sought to make the TCJA's expiring provisions permanent, potentially using the budget reconciliation process to bypass the Senate filibuster.

    Debt implications: Lawmakers have passed legislation that makes most provisions of the TCJA permanent, extending their impact beyond 2025.

    Debate over economic benefits: Whether the TCJA was a key factor in Trump's potential re-election is debatable, given the conflicting evidence regarding its economic impact and the range of other factors that influence presidential elections.

 

In conclusion, while the 2017 tax cuts were a significant legislative achievement during the Trump administration and a potential factor in discussions about the economy during a re-election bid, the extent to which they stimulated the American economy and influenced a potential re-election is a subject of ongoing debate and analysis, with considerable evidence suggesting a disproportionate impact favoring the wealthy.

 

American wealthy are working hard thanks to meritocracy, so helping the wealthy is good for all country.

Kaip naujas DNR mokslas galėtų padėti daugiau dingusiųjų žmonių šeimų


„Nauji metodai gerina gebėjimą identifikuoti net ir labai pažeistus žmonių palaikus.

 

Pasaulis susiduria su daugybe tragiškų įvykių, dėl kurių žūsta ir dingsta daug žmonių, įskaitant konfliktus Ukrainoje, Mianmare, Sudane ir Artimuosiuose Rytuose, taip pat klimato kaitos paspartintas gaisrus ir audras.

 

DNR pagrindu atliekamo identifikavimo technologija sparčiai tobulėja – susieja giminaičius, laikui bėgant, ir su labiau pažeistais palaikais, todėl galima surikiuoti daugiau dingusiųjų su vardais ir daugiau šeimų su artimaisiais.

 

Neseniai teismo medicinos mokslininkų, dirbančių su neatpažintų Vietnamo kareivių iš Vietnamo karo kaulais, pasiektas proveržis atspindi platesnį inovacijų antplūdį. Mokslininkai mano, kad, toliau tobulėjant, atsirandantys DNR sekoskaitos metodai galėtų suteikti aiškumo daugeliui sudėtingesnių bylų, susijusių su neatpažintais žmonių palaikais.

 

Kokie naujausi pasiekimai?

 

Dešimtmečius DNR analizė siekė didesnio jautrumo ir tikslumo.

 

Galingi nauji vadinamojo naujos kartos sekoskaitos [1] taikymai dabar padeda identifikuoti pažeistus palaikus. Šie metodai leidžia mokslininkams išskirti ir analizuoti milijonus DNR fragmentų, ypač vieno nukleotido polimorfizmus arba, angliškai, SNP, kurie yra variacijos atskirose genomo pozicijose.

 

Teismo ekspertai ir organizacijos, įskaitant Tarptautinę dingusių asmenų komisiją, kuri buvo įkurta 1990-aisiais, siekiant identifikuoti dingusius asmenis po karų Balkanuose, šiuos naujus pokyčius laiko dideliu šuoliu į priekį identifikavimo srityje.

 

Komisijos programa Vietname praėjusiais metais rado būdą įrodyti, kad didesnis laiko ar atšiaurių sąlygų, pavyzdžiui, tropinio dirvožemio, kuris paprastai būna rūgštesnis, paveiktų kaulų analizė dabar gali sukurti tikslius DNR profilius, leidžiančius identifikuoti. Amerikos karo mokslininkai neseniai padarė savo pažangą su palaikais, atsiradusiais dar Antrojo pasaulinio karo laikais.

 

Molekulinės biologijos specialistai vis dar pritaiko procesą skirtingoms aplinkybėms, tačiau nustatyta, kad kauluose, kuriuose trūko DNR, reikalingos identifikavimui, naudojant senesnius metodus, yra pakankamai SNP, kad specializuotos programinės įrangos pagalba būtų galima sujungti mirusiuosius su tokiais tolimais giminaičiais kaip proproanūkis.

 

Labiau įsitvirtinę metodai – mitochondrijų DNR ir trumpų tandeminių pasikartojimų analizė, kuri lėmė nusikaltimų DNR duomenų bazių kūrimą – dažnai reikalauja didesnio kiekio genetinių duomenų medžiagos ir siūlo mažesnį identifikavimo tikslumą.

 

„Dabar turime technologiją, kuri iš tikrųjų tiksliai nustato tas trumpas molekules“, – teigė prof. Matthew Emery, biomolekulinis antropologas iš Bingamtono universiteto Niujorke, tyrinėjęs DNR identifikavimą po gaisrų. „Galime gauti daugiau informacijos.“

 

Kaip vyksta šis procesas?

 

Pirmiausia surenkami žmonių palaikai. Vietname ir kitur mokslininkai teikia pirmenybę dantims su nepažeistomis šaknimis ir tvirtais, dideliais kojų kaulais, kurie geriausiai išsaugo DNR.

 

Kaulai valomi, kad būtų pašalinti nešvarumai ir paviršiaus užterštumas. Tada kiekvienas kaulo mėginys sumalamas į smulkius miltelius, kurie sumaišomi su cheminiais reagentais. Tikslas – išskirti žmogaus DNR į tirpalą, tačiau tai gali būti sudėtinga; reagentai yra brangūs, o tai, kas veikia su atskirais suirusiais mėginiais, gali skirtis.

 

Kai procesas vyksta, DNR jungiasi prie stiklo. Kitos medžiagos nupilamos, paliekant bespalvį lašą, kuriame yra milijonai bakterijų DNR ir (tikimės) dingusiojo DNR.

 

Tada mėginys patenka į naujos kartos sekvenavimo aparatą. Pastaruoju metu jie tapo greitesni ir patikimesni – vienas Hanojaus laboratorijoje telpa ant stalo, bet kainuoja daugiau nei 200 000 dolerių.

 

Sekvenavimo aparatas selektyviai jungiasi prie žmogaus DNR fragmentų. Jis išskiria DNR sekas, kurias speciali programinė įranga surenka į profilį.

 

Šis profilis lyginamas su etaloniniais mėginiais iš dingusiojo giminaičių duomenų bazėje. Algoritmai atlieka giminystės analizę ir nustato, ar galima rasti didelės tikimybės atitikmenį.

 

Kada ši technologija bus plačiai prieinama?

 

Naujos kartos SNP sekvenavimas jau daugelį metų plačiai taikomas archeologų. Jie naudojo chemijos ir skaičiavimo metodų derinį, kad sekvenuotų gauruotųjų mamutų genomą, ištirtų ryšius tarp neandertaliečių ir šiuolaikinių žmonių ir parodytų, kad sibiriečiai yra genetiškai susiję su ankstyvaisiais Amerikos gyventojais.

 

Šiuolaikinės identifikavimo programos, be genealoginių rinkinių, kuriuos naudoja tokios įmonės kaip „Ancestry.com“, atsirado lėčiau. Tačiau tai keičiasi keliose pirmaujančiose laboratorijose. Pavyzdžiui, nuo vasario iki gegužės mėnesio Ginkluotųjų pajėgų medicinos ekspertų sistemos teismo medicinos ekspertai naudojo naujus metodus, kad padėtų identifikuoti 51 amerikietį, kurių vardai greičiausiai nebūtų buvę įvardyti, jei ne naujasis metodas.

 

Tarptautinė dingusių asmenų komisija tikisi, kad jos projektas Vietname bus dar platesnis, leisdamas identifikuoti tūkstančius dingusių vietnamiečių ir optimizuoti metodus taikymui kitur.

 

Jos tyrėjai jau dirba Ukrainoje, Sirijoje ir Irake. Tačiau projektą Vietname daugiausia finansavo Jungtinių Valstijų Tarptautinės plėtros agentūra, ir nors šiais metais jo biudžetas buvo atkurtas, pinigai baigsis rugsėjį, nebent Jungtinės Valstijos ar kiti donorai įsikiš.

 

Mokslininkai pastebi, kad privati ​​​​pramonė ir teisėsaugos institucijos dvejoja investuoti į dingusių asmenų paieškos technologiją, nes išlaidos vis dar didelės, o atsipirkimas neaiškus.

 

„Infrastruktūra yra, bet paskatų nėra“, – sakė profesorius Emery iš Bingamtono. „Štai kodėl mums reikia šių tarptautinių organizacijų.“ [2]

 

1. Naujos kartos sekvenavimas (angliškai: NGS), dar žinomas, kaip didelio našumo sekvenavimas, yra masiškai lygiagreti DNR sekvenavimo technologija, leidžianti greitai ir ekonomiškai sekvenuoti didelius DNR arba RNR kiekius. Ji leidžia vienu metu sekvenuoti milijonus DNR fragmentų, žymiai padidindama genominių tyrimų mastą ir greitį.

 

Pagrindinės NGS savybės:

 

Masiškai lygiagretus sekvenavimas:

Skirtingai nuo tradicinio Sanger sekvenavimo, kuris vienu metu sekvenuoja po vieną DNR fragmentą, NGS gali vienu metu sekvenuoti milijonus fragmentų.

 

Didelis našumas ir greitis:

NGS technologijos gali generuoti didžiulius sekvenavimo duomenų kiekius per trumpą laiką, todėl jos idealiai tinka didelio masto genominiams tyrimams.

 

Ekonominis efektyvumas:

 

NGS žymiai sumažino sekvenavimo kainą, todėl jis tapo prieinamesnis įvairiems tyrimams ir klinikinėms reikmėms.

 

Universalumas:

NGS gali būti naudojamas sekvenuoti ištisus genomus, specifinius genus arba tikslinius DNR arba RNR regionus, taip pat genetiniams variantams ir mutacijoms aptikti.

 

NGS taikymas:

 

Genomikos tyrimai: Genomų struktūros, funkcijos ir evoliucijos tyrimas.

 

Klinikinė diagnostika: su ligomis susijusių genetinių mutacijų nustatymas, gydymo sprendimų priėmimas ir ligos progresavimo stebėjimas.

 

Reprodukcinė sveikata: prenataliniai tyrimai ir genetinė patikra.

 

Infekcinių ligų tyrimai: patogenų nustatymas, protrūkių stebėjimas ir naujų gydymo būdų kūrimas.

 

Teismo ekspertizė: asmenų nustatymas ir ryšių užmezgimas.

 

Žemės ūkio mokslas: pasėlių derliaus gerinimas ir ligoms atsparių augalų kūrimas.

 

Aplinkos mokslas: mikrobų bendrijų analizė ir poveikio aplinkai vertinimas.

 

Kaip tai veikia:

NGS veikia, skaidydamas DNR mėginį į mažus fragmentus, prie fragmentų galų pridėdamas adapterius ir tada amplifikuodamas šiuos fragmentus PGR metodu. Šie amplifikuoti fragmentai tada įkeliami į sekvenavimo prietaisą, kuriame jie lygiagrečiai sekvenuojami naudojant įvairius metodus, tokius, kaip sekvenavimas sintezės būdu (angliškai: SBS). Gauti duomenys analizuojami bioinformatikos įrankiais, siekiant surinkti sekas ir nustatyti variantus.
