The homeless coming in from out of state turns out not to actually be that prevalent in practice. In LA, for instance, only 18% of currently homeless residents became homeless while living out of state [0]. So if you could magically get everyone from out of state off the streets, you'd still be left with 82% of the homeless population, i.e. there'd still be a big homeless problem.
To a first order approximation, the majority of homeless are simply residents who lose a job or can't earn enough money, can't afford their rent, and end up on the street. Making a lot more housing available so it's not so impossible to afford is clearly an important part of the solution, which we seemingly can't do as long as progressive democrats are in charge.
Homelessness is, unfortunately, not a uniform block.
Some chunk are from out of state. Some chunk are mentally ill. Some chunk are addicted to drugs. Some chunk have physical ailments. Some chunk are fleeing abuse.
This is what makes homelessness so intractable. Even if you fix a chunk, that's probably less that 20% of the problem. Now, you've spent a lot of money, made no visible progress on the problem, and have a bunch of people clamoring about how you wasted money.
