Power corrupts people. Everyone powerful, even with the best intentions starting, becomes more or less evil because there is no good regulation and feedback. The transformation to communism needs people with power to ensure society stays on its path. So has every socialism country. Having a powerful minority ruling the population will cause discrimination and abuse because almost nobody will give back his power by choice.

growing up in a country with socialism past I can say that the change to democracy has changed more to the good than to the worse. Sure there were some things better back then. But overall it’s a better society now. Not ignoring, that there are many things really bad in our current mainly capitalistic democracy damaging it from inside. And doesn’t matter which country with a former socialism system you look into: the majority of people experiencing both say overall it changed to the better.

I hope one day humanity will evolve to a point where ideal communism will work. But I don’t expect us to experience this soon. And if we get to this point, we won’t need something like socialism for transition.

Not what I see but maybe my expectations are wrong. Still not what OP wrote and I was invited to explain my downvote to the initial post

Communism looks good. In theory. But for me it seems human mentality isn’t far enough evolved so it would work. Also China is far away from an ideal communism.

I can say capitalism is shit and all the other large scale established systems arent perfect too. No need to pick a side. We won’t develop something better saying one of these is already good enough
