Not all of it, there are some homeless who would be happy to get a job, yet a lot aren't exactly mentally stable enough for it.

Also, could you imagine going to a job interview dressed in rags? Even McDonald's wouldn't hire you. The whole "get a job" thing isn't as simple as people think, but of course no one wants to think about that because they'd be faced with an uncomfortable truth.

Attempting to truly help a homeless person requires a lot of faith and generousity, which are both in very short quantities these days.
