Former NFL player Michael Oher claimed that he was never legally adopted

i am not doubtng there are quiet content millionaires. I am doubting there are millionaires who could live the rest of their lives on the money tha have, and not be in the pursuit of more and more and more. And i am more referring to multi-millonaires not your ones who have a few million. My in laws are probably sitting on a few million dollars of saving/retirement (Shell Chem stock, pension, 40k, etc). But i would not consider them millonaires.

Seems like you're taking an objective measurement and replacing it with a subjective one.

If your in-laws have a net worth over $1M, they are millionaires even if they aren't flashy spenders or bad people.
