People are on the street because they don't have homes. If they had homes, they would be less depressed, less drug addicted, and less destitute and less likely to cause public problems. So just give them homes.

A major upside: if you lose your job, you won't be at risk of becoming homeless! it would allow you to take a much stronger negotiating position with your boss. It would allow you to take a much stronger position with your landlord regarding rent increases too.
