> the socioeconomical situation is exactly the same (because communism)
Not true at all. It might look that way to an american, but there are things like social capital, and it's not even true for financial capital. From USA perspective we were all equally poor, but from our perspective and "in our world", 300 vs 900 usd monthly wage is (was) a huuuuuge difference.
You have to consider that my parents and parents of my former classmates were raised during actual communism. Do you know how they raised children during communism? They beat them, because disobedience could mean death or lifelong prison or being sent to uranium mines - for the whole family. One bad word was all it took. And many parents haven't yet realized, even today's, that this is not the correct way. On top of that, during the 90's, rampant corruption has emerged, then the economical crisis, etc.
And then of course the teachers - their role during communism was different that what it should really be today, and many have not realized yet.
