Poverty changes how you act, in non-obvious ways.
It’s clear that the good quality screwdriver which will last a lifetime, for $6, is better than the junky screwdriver you’ll have to replace in a year for $3.
What slips past folks who’ve never lived in poverty is that if your choice includes “and the other $3 will buy flour so you can bake bread all week, otherwise, you get no bread” then you buy the cheap junk screwdriver.
And then again next year.
Multiply that by every single small purchase decision you make and you’ll quickly see that when there isn’t enough money, it can be almost impossible to escape.
