I used to think this and then it stopped expanding. I have very low needs. Just enough for healthy food and some tennis equipment and I'm happy. It got to the point where I was earning much more than I could justify spending so I decided to change careers for something that optimised for lifestyle over money and now I'm much happier. People think that more money = more happiness, but I'd say that you need more money when you're unhappy. Money buys comfort but not happiness. Ironically when you're happier you need less money.
Most people do eventually reach that point. However, for most people that point is significantly above where they are. There are plenty of things I would like to buy that I don't have the money for. I have a nice life. I had my staff engineer income, but there are things that I can't afford to buy that I really would like.
I'm sure if I was a multi-billionaire, I would have no clue what to spend a large portion of my money on. An Expensive cruise would be fun once, but I don't think I'd want to do that more than maybe once a year.
