I found this article written by a libertarian. He claims that he's writing a libertarian policy, but I think it's really more like common sense.
This is my favorite quotation from the article:
"When people get checks from the government, they tend to think of this as an entitlement. They are getting money in exchange for doing nothing. They learn that this is how you get money -- you take it from others. Taking money from others is what criminals do.Productive people get money from other people by exchanging something of value. "
