If I were Filthy Rich
By bartexas+27 We Asked the Experts: Exactly How Much Money Do You Need To Be Happy?
Interesting read for perspective. Copy and paste link into incognito window if you hit a paywall.
Article is from 2017, so adjust for inflation, but, basically, it says at $190M you can lead a NYC UES lifestyle with seats on a charity board, kids in private school, spend $1M/year on art, weekend house in the Hamptons, and another vacation home.
ETA: Despite the title, I think what is interesting is the dollar amounts mentioned and the corresponding lifestyle, not the happiness question.

+21 @HEMIfan17 Multiple studies have concluding that when people when the lottery, there is no increase in their overall happiness. But I think they were looking at things wrong. It's not the money. It's what you do with it that counts. If you let people bleed you dry, of course you're feel like sh\*t at the end of the day. As a famous french playwrite once said, "Money may not buy happiness, but I would much rather cry in a Jaguar than on a bus."
+17 @bravogolfhotel A lot of it has to do with one's reasons for being unhappy. If you're unhappy because you're feeling distant from your spouse , a lottery win may actually make that worse (but it will enable you to afford a top-drawer divorce lawyer). If you're unhappy because you're working as hard as you can and you seem to end every month with $0.68 in your checking account, a lottery win has the potential to cure that permanently.
