Should Congress "rethink" the nations welfare system?

I realize that there are people on welfare that genuinely need to be there for their physical and mental conditions. i realize that people on welfare also need a place to live. i have no problems with those genuinely “in need”. but, what about those that are milking the system for all its worth? you know the people i am talking about. they could work at doing something. and, what about the people on welfare that always have a roll of money in their pocket? was this money gained through an illegal activity? i have seen this so many times in welfare-assisted housing. should people on welfare be tested for illegal drugs? i read this question earlier on Fluther and this is what came to mind for my question: is it time for the Federal Government to “rethink” the whole welfare system? Is it time for new rules and regulations to “weed out” those people that are committing fraud at the taxpayers expense?
