The threshold for top 10% is $2 million net worth. That's it. People are in psychotic amounts of debt.
Bottom center of the image is a $2 milly house in a suburb of Denver. Backed right up on your neighbor so close you can smell his farts.
All you have to do is own that house paid off and not carry a CC balance month to month and drive a paid off car and congrats you are "RICH"
