First, we spend far more on Middle Class entitlements (Social Security and Medicare) than we do on "Welfare".
Secondly... I have mixed feeling on the second point. My sister lost her eyesight and could no longer work as a nurse, but SSI still insisted she try to do other things. On the other hand, a slug like Ray from Cleveland can not want to do certain kinds of work, and he's fine.
Third point- talk to your anti-abortion nutters, then. Can ban abortion and then not pay for the babies that result. But the reality is, most people on welfare are on it for less than four years.
Fourth point - Most people are only on welfare for a few years.
Fifth- Who is going to run this training?
