Money is not how you count if you made it. I made as much as OP at that age (and am now a few years older) and I'm very far from making it. Millions don't go as far as they used to when everyone around you is even richer.
With all due respect, your comment suggests that you were spending beyond your means, or keeping up with the Joneses. Millions go very far if invested properly and drawn down properly so that the principal is never touched. If you're spending the millions instead, then yeah, that's definitely not gonna go far.
There's a huge trough in what you can do with what you can buy when you earn between $80k a year and ~$8m.
It's the same shit just better.
Your shitty commuter house 3 hours out of town is now a mansion 20 min outside of town. Your shitty 1990 ford fiesta is a very nice 2020 BMW. Your shitty healthcare plan is a great healthcare plan, but the main difference is how nice the plants at the doctors office are. If you want to get a divorce your new partner looks a lot better than your old one. Your furniture isn't chipboard from Ikea, it's hand made ethically sourced mahogany. Your flights aren't economy class, they are business+/first class. You don't have to run your washing machine, you pay someone to do it.
If you want anything interesting, like say a nuclear reactor in your basement, or a jet two seater Canard, you can't afford it because no one makes it. Unless you have the connections to start a company to make them, or have literal billions lying around, you don't have the resources to do anything but live middle class+.
Sure if you try to go up in quality you hit diminishing returns. Not quantity though. $80k and you're working for the rest of your life. $8m and you retire at the end of the year.
