Well, there's a lot to comment on here, I'll address just your last sentence.

If you owned a deli or corner-store would you be willing to hire someone with criminal record?

Would you be willing to hire someone who doesn't have a home?

Keep in mind that not having a home means they probably have no way to consistently keep themselves clean. And what do they put on the employment application for their address? And how good of an employee is someone going to be when they don't know where they're going to sleep at night?
