Eliminating homelessness, eliminating illiteracy, eliminating hunger, increasing life expectancies, increasing graduation rates, increasing quality of life, actually existing socialist countries accomplish incredible things (some more than others, admittedly). They're not perfect utopias, but you can't ignore the context they exist within (i.e. they're still developing countries and they exist within US global hegemony)
I'm sure you have some specific criticisms of China or Cuba or whatever, but they're doing pretty fucking good considering what they're up against.
While you keep on dreaming of utopia, I'm more concerned with defeating than US empire in the real world. Anarchism can't.
USSR “solved” homelessness putting people in prisons and psychiatric hospital… and even then there still was homeless people. Authoritarianism doesn't work.
And Berlin west was a weird political situation, but my argument still holds. People flee DPRK or China…
