In Taiwan the homeless rate is very low because having a homeless relative is shameful. Affluent people do whatever it takes to ensure that no one in their extended family is out on the street in order to save face, even if they don't particularly like those relatives. No such culture of family responsibility exists in the US.

As an island nation, Taiwan also has a somewhat easier time preventing narcotics smuggling. Whereas the mainland Chinese Communist Party has covertly targeted the USA for "Opium War 2" by tacitly allowing the smuggling of fentanyl precursor chemicals to Mexican drug cartels.
