Sure. Nobody here is suggesting we, like, demolish all existing housing and force everyone to move into apartment blocks constructed exactly with the architecture they used under the Soviet Union or Maoist China. I'm just pointing out that people tend to write off those housing units because they don't look pretty, when the reality is that there are some significant upsides to actually living in them.

Fact of the matter is that social housing can and does work and has been an extremely effective tool for alleviating housing shortages all over the world (including quite a few capitalist nations in the modern day, by the way). You just have to do it right and build with the intention of fostering diverse communities rather than warehousing the poor out of sight as we did here in the States in a prior era.
