If you “leave it to the free market”, you will just get further sprawl of single family homes; Los Angeles-ifying the rest of the country. Maybe at best sprinkle in some paper mache five-over-ones in there. The US does need more, denser housing, but will never be provided by the free market.
The actual “Chinese” solution would be to take genuinely blighted areas of a place like Detroit, build very dense, affordable public housing, provide tons of services and public transportation, and ensure local residents get priority. It would be a solution everyone would love, better than Americans could possibly imagine, but the idea that this could be done by the free market strains credulity.
Edit: kicking myself for missing the bigger point in my original comment. In China housing is largely decommodified, it’s something to ensure everyone has. Meanwhile housing in the US is a speculative asset driven by exchange values first and a use value second. Of course there is a speculative element in Chinese real estate but it is not primary. This is a direct result of socialist vs capitalist relations. Since changing THAT isn’t on the table, the US cannot do what China is doing.
Americans - even Americans like Bernie - have an incredibly shallow understanding of history. They will recall a few key words and ideas from their history classes, but probably even more just from the environment around us, which is skewed towards reproducing capitalism. So they understand historical subjects only at the most basic level and usually not in a way that is correct.
I don’t think historical ignorance is a huge problem in itself. The bigger problem is, despite their incredible levels of ignorance, Americans will insist their understanding of history is inviolably correct; No American will ever say “well, you sure seem to know a lot about Stalin, I don’t know anything so tell me more”. Suggest anything about Stalin outside of “authoritarian dictator who kiled millions and made everyone clap” and Americans will INSiST you are wrong and they are right, regardless of who has actually put in any work.
