A lot of people do little more than sit around waiting for their social support benefits. However, much of that is due to the way the system is - deliberately - set up, as opposed to willing laziness. What is a person, say a single mother of 2 (of which we have WAY too many, but that is another topic) supposed to do if the system is set up so she can get $600 housing assistance, $300 in food stamps, $200 in child care assistance while working part time and making $800/mo, but if she works full time, increasing her income to $1200/month, her housing assistance drops to $300/mo, food stamps drop to $180/mo, child care drops to zero? She stays at part time employment, and spends the rest of the day waiting for her benefits.
The system is deliberately set up to force the poor into dependence on government programs, so the liberal democrats can come around at election time and tell them to vote D or they will lose all their benefits to the mean, nasty hate-the-poor republicans. The figures used are very rough approximations, but the end result is very real. People are literally punished for trying to do more for themselves (ie: lose more in assistance than they can make up for by working more). And since the welfare reforms that took place under Clinton and the Gingrich Congress, they are sneakier about it. Used to be a single program would cut more than a person made by working more - and the people caught them at it, and called for "hand-up, not hand-out". Now they make sure they spread assistance over many programs, with low cuts in EACH program, so they can still keep social assistance programs an economic trap for the poor.
