they're about as close to socialism as anything that ever worked.
look, you can say hey these countries are socialism light, or soft socialism, or whatever, but they WORK a fuckton better than anything the hard core types has ever accomplished. And if you call China socialist then ANYTHING is socialism. Pick a lane, you don't get it both ways.
On the other hand, the terrible object lesson examples for socialism litter the history books. I'll take a soft socialism 5/5 times before gambling with Pol Pot, Stalin, Xi, Kim etc., you do you.
