Smaller countries than the USA do this and they are not socialists nor do they have the problem with drugs,welfare and unemployment we do.

Allowing homelessness to exist at its present level serves a purpose in capitalism of making sure that wages stay low or at least stagnant as workers realize they may face this if they don't stay obedient enough to employers as well as providing a class of wage slaves-the actual homeless- who are desperate enough to accept dangerous, unhealthy, shit jobs that people with homes would refuse to do.

You mean, it's cheaper to have government take money from some people and buy the houses to give to other people?

Cheaper still, I wager, would be finding ways to prevent people losing their homes in the first place, no?

Yes it is..

If someone doesn't have an address and phone getting a job is virtually impossible.

It would be nice that everyone had a home to go to.
