A LOT of kids finishing school would be quite content getting cheap housing, eating junk, and playing video games or hanging out all day every day. The longer they do, the less incentive to be productive.

I wouldn't "do nothing", but before meeting my wife I was on track to reducing my expenses to near zero with intention of "going off the grid" with vanishingly little interaction with & contribution to society.

BTW, a suitable gun is about US$500 - a lot cheaper than paying people enough to not hurt you.
