"Poor" is why razor blades are behind a glass case at Walgreens. Because people steal razor blades, not (just) to use, but to sell at a discount to other poor people. There is also the interesting situation of "newly poor" people getting crushed much faster than people who have been poor a long time. There are community safety nets that bubble up from everyone being cornered all the time. You don't go to the mechanic…
I'm not gonna speculate on what other things could have been more responsible but I have my suspicions.
