I've spent most of my life on the lower socioeconomic ladder, I understand the copium that poor folks use to get through life that seems designed to exclude them and keep them from having nicer things.
I specifically commented further up that it's bizarre to claim that money doesn't buy happiness, because it pretty obviously does, at least up to a certain point. But I also remember times in my life where I've comforted myself by pretending that being poor was a virtue instead of just being shafted by life and circumstance and I've heard similar thoughts expressed by others.
Honestly that mostly seems to be a sour grapes thing to convince themselves they wouldn't be happier with more money.
