once again, even if you're right, and a chunk of society decides "screw volunteerism, I'm going to lay on the couch and eat flamin' hot cheetos and drink root beer," SO WHAT? It's a society of abundant resources. We have large people now who "live on the dole" in some way or another and it hasn't brought the market economy crashing down.
If anything it's always too many people pursuing too much that inflates bubbles and causes crashes. The next big one is everyone irrationally cramming into higher education thanks to government loans. I'd rather a big chunk of those people be on basic welfare. I bet it would cost less than the inevitable bailouts.
