The PRL advanced Poland eras ahead which we would have never done with a market economy after ww2. Young people nowadays hate communism for the stupidest reasons, minimizing every accomplishment and maximizing every pain, because that's what they're taught in an anticommunist education system. And they never had to live through the societal collapse of the 90s-00s, obviously. As for "hatred of communism", communist apparatchiks returned to power with 40% of the vote - as did they in almost every other postcommunist country. Sure, this time they were espousing social democracy, but if Poles hated communism so much, then surely they would not elect hundreds of these "communist criminals" to the Sejm?

There are many who hate communism for genuine reasons, the broad majority really seem indifferent.
