Who is in the Lithuanian middle income class and why are they not happy?

 "The OECD says we should include in the middle income class those households that receive from 75% of  median Lithuanian income up to 200 percent. The last number is twice the median.  

Linking the median to the average disposable income of a household, we would talk about amounts from 900 to 2300 euros per month per Lithuanian household. The annual income would be approximately from 11 thousand up to 28 thousand with some calculation error.  

Now, according to the OECD, every sixth middle-income household faces a threat to the workplace due to automation, digitization. As a result, the challenges of the middle class are becoming more relevant in the future."
