I think it's a matter of cost-benefit. On one hand, you have a rat race of soul crushing minimum wage work, always one slip away from the investment in hard work evaporating and being dropped right back on your ass. On the other, you sacrifice any chance of advancement to live with few obligations other than what it takes to survive. It might be more accurate to say that the person didn't choose to have this dichotomy, but given it, they chose the latter option.

Our culture is rather obsessed with the idea of wage labor as morally imperative and necessary to provide life with self-meaning. I can sympathize with the idea that to some, wage labor might subtract meaning from life. Especially if it's working at a Burger King to pay for a room at a flophouse.
