Disparity of wealth isn't how most people define being rich/poor. Most people compare themselves to their 5-year-ago self (or their parents, or their childhood, or their expectations), and as long as they're doing better than expected, they're rich.
It's just that people who compare themselves to others tend to be disproportionately loud. If you compare yourself to yourself and come up short, you have nobody to blame but yourself, so of course you're not going to crow about it. If you compare yourself to the people you hear about on the news and come up short, obviously they must have cheated.
