This is well known. There is a paper from the FDIC that points out that if you make lending decisions based on platform (iPhone vs android or macOS vs windows) you are likely discriminating because iPhone and macOS skew older, richer, and whiter. It is one of the things that makes letting ML have access to big random data sets for lending and finance so dangerous.
I suppose it depends on what feels rich. The kinds of places you go when you are actually rich cost thousands or tens of thousands of dollars a day, and they have shops where most of the stuff costs tens or hundreds of thousands, and everyone around you is carrying, flying, driving, or sailing things that cost hundreds of thousands or millions.No one I know who makes 300K (after tax) - unless they have a net worth that is in the 10s of millions - feels rich.
First, a sale of $14M doesn't get you $14 - you'd get less than 10 - best case.
Second, your after inflation return in the current environment may be quite ugly - $300K or $400K a year will not feel rich in any east or west coast city.
Nah, 14M isn't enough to practically afford a NetJets card - unless you are making about 5M - in which case you'd expect to have more than 14M. I work on WS and am very senior, so often fly private, and I have a bunch of friends who always fly private. The generally accepted threshold is about 25M with an income of 2-3+ before it makes any sense. I suppose that if you had no other expenses (like a nice house and cars or a thing for vacations or art) you could afford it for a while as your only extravagance, but it isn't that special. In fact, for long haul, 1st on an airline like Cathay or Singapore is better than a G650ER in many ways. For short haul domestic a private jet blows away commercial, but mostly I'd rather spend my money in other ways.
