Not necessarily rich, we all have hobbies we spend more money than others on. I'm not rich but I have a nice home theater setup that I could afford because I don't spend money on other stuff that I consider a waste when others don't (ex: I haven't been to a bar in about a decade even if my friends do go fairly frequently).
When you're disabled barely scraping by on SSDI - with the occasional bit of charity in as pinch - then just about everyone is rich to you. And that's just one example. Someone with 3 kids and 2 jobs, 6 digits of student loans and a crap job to show for it, just as much medical debt, or any of a number of shitty - and appallingly common - life circumstances is gonna be in a similar boat.
