Suppose you *could* through constant labor, strenuous planning, & deprivation manage to feed yourself & your family on a tiny budget, that would still be extreme poverty.
I hate that people who aren't in poverty try to explain to those who are "no, really, you can survive. You just need to find a way to suffer a little more."
The problem is not a lack of ingenuity & creativity. The problem is poverty. No one should have to struggle every moment of every day just to live.
