You're way too cavalier on your assessment of poor people. Why do you assume all poor people are on welfaire? My poor grandmother, who adopted me, worked for years as an LPN, no easy job, and that wasn't temporary. She was never on welfare, but we were poor. I don't think being poor is a "temporary" condition for many, many people.
I don't assume that. Many poor people work. My point is that in America people have every opportunity (often at public expense- think schools, libraries, skill training programs) to improve their lot in life.
The fact that some choose to stay poor, and make those choices that made them poor in the first place, is not my business, as I cannot force them to make smarter, better choices.
