I had a co-worker who thought he had a typical american childhood because he didn't consider his family wealthy, even though they had millions of dollars of networth over 30 years ago. Him and his 3 bothers went to a very exclusive private school that was 50k a year per child, but since his classmates were mostly "old money" that were from family worth 10s to 100s of millions of dollars, he was picked on for being the "poor" kid, so still thinks of himself as having a middle class family.

He was also the only person I've seen who made me consider that "afluenza" might be a real thing. He would get super bad stomach aches and diarrhea any time he ate fast food because he was mentally conditioned to believe it was disgusting. He even went to the doctor about it, and was told it's all in his head, it's just the thought of eating poor people food made him ill.
