Because it does not cost a lot of money if you want to live a hand-to-mouth existence. It is like asking how do subsistence living work. You make to do with what you have, what you can gather and do something to earn you occasional cash. There is no long term thinking here, no optimism for future. I do not think this leads to a healthy society. But the point is that they do not have a lot of bills to pay and they do not care about the remaining.
