ideas get cash cards for homeless car wash?

A typical fascist idea.

empty of any human consideration or empathy

Control those poor homeless people whose homelessness is no fault of their own.

How about a car wash for the rich and pay them below minimum wage.

Muppet!

If someone works to earn some money, what right do you have to limit how they use it?

This is not simply a libertarian argument: look up the research on cash grant programs. Abuse in cash grant programs is much less than you might guess, and because they are so cheap and simple to administer, their efficiency at achieving their intended results can be very high.

Just give people cash.
