1) The US approach to multiculturalism, drugs, mental health, and social safety nets has been different from most of the rest of the developed world since the mid-20th century. 3) I wonder what happened culturally and economically from early to mid 2020. Quite mysterious. 2) Economic prosperity, increased surveillance, and simply learning that there are better ways to engage in the drug trade than murdering people over street corner turf, probably contributed to the decrease in violent crime. There was an article a while back about how gangs in LA had essentially transformed themselves in the past few decades—less standing out on street corners, more delivery/pick-up kinds of operations; I can't find a link right now. They still do some of the same stuff, but there's less of it. Also, if you buy the environmental lead explanation or abortion explanation, those are available too.
