alt Hacker NewsI think it’s largely just that people just don’t want to live near poor people, because they think they have bad culture/values/behavior, and will be risky to live near.
Based on comments I’ve seen at city council meetings about this stuff, there’s also some aspect of feeling like infrastructure is already overstressed, traffic is already bad, etc, which is largely an artifact of car-centric development patterns being incredibly wasteful/inefficient, and capping out at relatively low densities. But the existing development pattern is usually not a good fit for mass transit - the utilization is usually too low.
I think the California approach of aggressively upzoning near public transit is pretty good, except that it might cause resistance to public transit expansion.

This kind of thing becomes a self-fulfilling prophecy when all the poor people get crammed into one place.
Singapore does it right by having high quality housing which happens to have a certain amount subsidized for lower income people. You get a mix of incomes and not a slum.
A lot of California's housing development also incentivizes this type of arrangement: permitting can be fast-tracked and local NIMBYs can be steamrolled if a development allocates some, but not all, of the development to be designated as affordable.
