"what is keeping everyone from just quiting and sitting at home getting money from hard working people"
Laws. You can't be on Welfare more than 5 years. Also contrary to what you may think, living on welfare isn't very glamorous. Go ahead and quit your job and collect. See how awesome it is.
Maybe you deserve to make MORE money. More for them doesn't/shouldn't mean less for you. Wealth is accumulating at record speed at the TOP while the middle shrinks. The money is there, it just needs to be freed up. If they won't pay the middle and lower classes more for their work that makes THEM wealthy, then they should be taxed more to provide for the rest better.
