The same poor people you are whining about seem to have no problem providing an ID when signing up for government aid. Or renting a movie. Etc, etc, etc.
Just how many poor people don't have a driver's license? And in a lot of states a state-provided photo ID can be had for nothing. Hell, they'll even come to your house and take your photo and make you an ID card if you have no way to get to them.
Tempest in a teapot.
