Worrying about money is one of the worst worries. It's like having locked-in syndrome, except you're still moving around and doing things. Your head burns. If other people are not having money problems, it pisses you off because it reminds you that you're limited in the ways you can express your agency in the world, and they aren't. Worrying about money is anger-inducing because it makes you think about time: how many dollars per hour, how much salary per year, how many years until retirement. Worrying about money forces you to do endless math in your head, and most people didn't like math in high school and they don't like it now.
