I grew up a Value Village & Kmart kid, home bowl-based haircuts, Halloween costumes out of what was lying around, & *tons* of insistence that I didn't need things because my sibs didn't quite connect asking for things with my parents always fighting.
Years later, I still wonder if I'm playing out Pratchett's economic theory. Yesterday I found 2 pairs of shoes for 25CAD apiece & felt proud of myself. & that's fine (money's tight) but *could* I mentally invest more in better things if it weren't?
You highlight a really important point: later in my life, I met others who'd experienced financial hardship, but *without* the vicious antagonism that consumed my parents. I've met people who grew up in poverty with a sense of solidarity rather than shame, & that can make all the difference.
So I don't doubt the hard years continue to shape your thinking--but I'm cherishing the gift you gave your son, in being united even in hard times with your spouse. Well done to you both.
