Except if they're doing drugs (even if it's to help with the pain of being poor and alone) giving them money just means they'll just buy drugs to "Help" their addiction.

Except the really poor who can't cover their needs can get government housing (section 8 etc) and welfare and all that, the problem is the homeless are either mentally ill (like ptsd veterans etc) or drug addicts or drunks or disabled.

And if they had little money they'd use it to pay for the necessities first (light and water bills and rent should come before everything food can be provided from food banks or churches)

If you want to help the homeless provide them with some place to live and some food. Help them get back on their feet with job interviews and clean them up. (But once they get a job they will be expected to pay "rent" for living in the housing...even if it isn't a lot)

Giving them cash is just throwing away money because the vast majority are going to use it to self medicate and that solves nothing.
