Most homeless people can't get jobs. We can go home, take a shower, get dressed, etc - the homeless guy doesn't have that advantage. Every job application I've ever seen asks for an address, I would imagine not having one automatically puts you at more of a dis-advantage than skin tone or gender ever could.

You have a computer, maybe you have a car... you can spare a quarter. Too many people find excuses to not give to the homeless - if you're worried that he'll buy beer with your money and you care at all, buy him a burger or a cheap blanket. Just don't make excuses, enough people starve and freeze in this country every year.
