On a similar note, we should provide food and housing to the homeless. It shouldn't cost more than $10,000 to feed and house a person, probably much less. I've heard that the current system costs $250,000 per homeless person, so doing this would save $240,000 per person helped. We do already provide free food and housing, although through a very complicated and expensive and inconvenient system:
* Free ride to the nearest hospital: just call an ambulance. In many places, they can't refuse. Cost to us, $1,000.
* Free short term food and housing: a hospital stay, must go through Emergency Room. $500-$1,000 for the visit, more if they stay. Also, they'll be ahead of you and you'll have to wait half an hour to get treated. Some of them will actually injure themselves instead of faking it, and that costs even more. See here for ER folks venting to stay sane, a lot of them are about homeless people.
* Free long-term food and housing: Commit crime, go to jail, get food and warm bed. Cost ~$100,000 per year, plus court costs. Decent winter accommodations.
* Petty crime to acquire food and accommodations (see if anyone would hire a homeless person).
Note that you're already paying for all this, whether you like it or not -- through taxes, through higher hospital bills, through crime and its results. Man up and cut out the middleman, and everyone will be happier.
