How do illegal aliens find work? You also ignore friends, family and private charity. My wife and son would probably be homeless were it not for me. If I was so hard hearted there would be two more homeless people. I am truly a saint.
Let us speak of the most humane philosophy, in the long run, social darwinism. Survival of the fittest ain't always pretty, but in the long run it benefits society by ridding us of the insane, the slothful and the irresponsible. Every American has an opportunity for 12 years of free education, every American has the power to decide what level of drug use they should engage in. No American should be forced to pay for the housing of some dopehead, no American should be forced to pay to house some nutcase who won't take his medication. Nor should that nutcase be forced to be medicated. Individual liberty, what a concept. Individual responsibility, what a concept. If you want to help the homeless...do it. Don't force me to pay to help stinkin' bums.
