I've seen example of people selling their company, retiring early and stay low-mid budget. One particular example is very wealthy but live in a small house, drive a 10y old compact hatchback car. You wouldn't know his fortune just by looking at his habits. He enjoy more a BBQ with his neighbors than going to expensive places to eat and help around when someone in the village needs an additional hand. He is still probably spending a lot more than I do traveling on holidays and he has nicer furnitures but he is still doing it like most people do, only a few weeks a year when the kids are out of school. What he has is the ability to justify buying expensive but sturdy stuff that last, instead of things that break and have to be replaced on a regular basis.
But it’s a bit ridiculous to get 42 million USD and not be satisfied. And the original comment is ridiculous to suggest that it’s not sufficient compensation.
If you make 25k/year getting 1M is almost as good as getting 42M, because you are not used to thinking about anything you can do with 42M that you can't do with 1M. However, if your salary has been 10M/year, you most likely can easily see many ways to spend 42M, which are not something you think about often when you make 250k/year.
Does this make sense?
There’s nowhere in the world where the cost of living requires $10M/year. To spend that much money you are forced to spend it on high-end luxuries. Of course there are people who could easily consume that amount of money, but most people on that income would put it into investment instead of consumption.
It's a different question how many people actually spend 10M/year - I have no data about that, but I can easily see myself spending that much if my income has been 40M/year for several years. To me personally spending that money would not necessarily mean buying some high-end luxuries. It would probably involve trying to make some changes in the world and influence things. But yes, luxuries and interesting experiences too. If you're interested in this question, try finding more information about lives of famous rich people.
