I don't see how your questions follow from my comment. No where am I trying to argue that resources aren't limited. I just said you will have to decide what to do with people who don't meet your requirements, and that you may spend more money checking that people are meeting requirements than you would save.

I also never said that letting people starve who can't or won't support themselves is morally indefensible. If you want to argue that it sucks but is a better alternative than what would happen if you tried to save everyone, it doesn't make you an immoral person. My only point was that you have to think about what you will do with the people who don't meet your requirements.
