Just because somebody has it worse doesn't mean that it's okay. If you stub your toe, should you not be able to complain because I broke a bone in my forearm when I was 6 and the doctor had to snap the other one with no sedation/painkillers so it would heal correctly?

Plus, cost of living is a thing. They may have been richer than 80% of the population, but I bet their cost of living was higher than most of them as well. Minimum wage in my state is $15 USD, twice the federal minimum, and somewhere around 80% of the workforce in the state capital has at least a bachelor's degree (the highest percentage of workforce by city in the country). Despite this, the vast majority commute from outside the city every day for work, because the cost of living inside the city is so high most people can't afford to rent an apartment. I made more money in 2022 than the bottom 51% of Americans, and I can't afford to move there.
