The number of people on welfare has been skyrocketing. Why? Because once they get on welfare, we make it almost impossible for them to get off. In order for somebody who gets on to get off, he or she has to be able to have a really good job, because to get off gradually, to earn a little bit, now doesn't pay...Under a negative income tax you would give people, give the poor people, a possibility of getting off gradually. They can earn an extra $1000 or an extra $2000 and be better off.
