I think this is a mantra for poor people living in industrialized countries globally. My parents were dirt poor, but they had nice clothes. I instilled this philosophy in my sons. Clothes give us dignity.
The childbirth patterns of more prosperous people are interesting, and often short-sighted about the future needs to maintain future wealth. I can’t understand why people “make it” and then forget to make kids to maintain it. I know some rich White southerners who believe in having lots of kids to keep the population high. I thought it was crazy. Now I see the madness manifesting.
