It's certainly enough to "live comfortably", as most of us think of the term. I chatted once a bit with a rather high income individual who was open about what he spent money on and he claimed his income disappeared quickly, he laughed and agreed it was his fault. These folks tend to live in "nice houses" with large yards needing expensive maintenance for the pool, landscaping, maids, etc. Then they may belong to an expensive club or three, and donate to the local arts funds etc. (which would be deductable). They drive expensive cars of course, might have three of them. One wealthy person we knew in France had a personal chef. $$$$$ and a boat.
I think we live "comfortably" here but I'm watching our expenses and there are some things I'd like to do and don't.
