So what? USA has more empty homes per capita (17 million for 330 million citizens, vs. 60 million in China for over 1.3 billion). If you compare it by density it looks even worse for the USA.
In any case, it's not really a useful, or meaningful metric anyway.
the grandparent poster was mistaken (the 90 million represented the amount of people the empty housing could house, not the amount of empty homes itself) so I found real number and included the link.
Yeah but out of that USA total, how many vacant properties are from foreign investors, let alone Chinese investors trying to stash their wealth out of reach of the CCP.
