I agree, but only because I routinely speak with people who make double that and still struggle to pay monthly bills. Short answer: financial outcomes aren't about the number (above a basic threshold), and they’re almost entirely a function of behaviors & (some) luck.
Paying more is still a valid form of defense against petty corruption, though.
What often baffles me is the "buy a whole bunch of things on credit", and then get laid off and have not a penny left.
I've seen stories of actors in Hollywood banking $15M from a movie, buying all sorts of property with mortgages, boats, cars, all on credit, then losing it all due to default without that next movie.
