Communism as it has been tried was indeed flawed af. We're going to need something else if we want to survive and be much more extreme than that. Your old communism was still a money economy, with the inherent problems thereof, functioned badly with greedy and fearful people at the top.
It's always funny to me that when you tell them capitalism sucks you are a fan of 20th century East bloc regimes. No I'm not a tankie. Tankies are extremely stupid.
