Cuba, Vietnam, and Laos for starters China went from a century of humiliation to a superpower in less then a century thanks to socialism. The USSR was better than the feudalism before it or the dictatorships of the bourgeoisie that came after it by a wide margin. For a place much poorer than the US, they had similar nutrition, better education, more rights for women both legalistically and practically.
Oh, throw in east Germany too. Do you know what the Stasi did to the lgbt movement that they saw as subversive? Destroy it by ending discrimination against gay and trans people, including a massive education campaign to eradicate homophobia and transphobia and state funded gay bars. Compare that to how the US was treating gay people at the time.
Yes, yes. It is cool and subversive to support capitalism, or at least oppose its alternatives.(aka support capitalism) You're part of the cool club of people who act in the interests of the bourgeoisie and not of your own class. A real independent thinker.
(Not that any of us are independent thinkers, but one of us is defending the powers that be and calling the other a chatbot)
