Some of this is poor people stuff but some of it strikes me more as depression/low self-esteem. Of course one can lead to the other and that may be the case for the author, but it’s not only poor people who feel depressed or suffer with low self-esteem so some of it seemed out of place. Obviously examples like the guy who didn’t notice his paycheque bouncing are a sign people around you are wealthy though.
That means you’re wealthy now. I grew up fairly poor but with 10+ years in the industry I probably wouldn’t notice a missing paycheck for a while. I’m making 5-10x more than as a teenager. Doesn’t mean I grew up as some kind of an aristocrat
