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…
The US puts more people in prison than the USSR ever did, yet its homeless population is huge.
And there isn’t a giant wall around China lol
Authoritarianism doesn’t work, whether capitalistic or communist.
And travel is very restricted in China.
