But in Europe I've mainly seen people with mental/drug issues and those from fringe groups like gypsies. There have been plenty of projects involving giving them housing for free, but it never works. The neighborhood quickly becomes a no-go area with constant police presence. They sell all the inventory for drugs, flats become dirty and infested etc.
There's a reason these people are homeless and that has to be solved first.
But if regular people are homeless then the system is really failing them on basic welfare :(
If this is common for regular people in the US then the system is really letting them down and I'm starting to understand why people vote for Trump (though I'm sure this will only make things worse for them)
I expect you are correct about the votes for Trump. Voting for change without understanding if that change is likely to be good or bad. Public policy issues are complex and most people probably don't have the time or energy to understand exactly what they are voting for.
There's very few people homeless because they can't afford it even despite the insane rent prices. Usually it's a ton of untreated mental issues and/or drug addiction.
Building more houses will help regular people a ton but not the homeless. More shelters will. Good and affordable mental healthcare too. But that's "communism" so I guess that won't fly in MAGA America.
