My wife and I make okay money in a middle class area, but, due to a combination of good luck, and contrived to circumstances, we recently got to watch a college football game in the stadium’s super executive corporate sponsor level suite. It was awesome. Open bar, amazing catered food, and people networking all around me who are clearly in the c-suite of their respective companies. I had a list of crazy things I was going to say if someone asked me what I did, but it never came up.
Having seen how my buddy lives with his family being in the ~$100M net worth range and them overall being quite modest people, I’d 100% believe someone well above that and/or wanting to flaunt their wealth in a stupidly ostentatious manner would put a pool in their kid’s room.
