Thanks, now I think I understand that you're saying once you get above 50 million, the amount isn't meaningful.

For me I can see where even $50 million would put limits on my spending. I would love to have a personal super yacht with well paid crew and be able to cruise wherever, whenever. I wouldn't feel that $50M would be safe enough for that, whereas $1B would be. Not that I'll ever have the opportunity to test that.

Some projects would take more than $50M, such as buying enough politicians to make the country a better place. The problem is, most people who lean more altruistic with spending are likely not to accumulate large amounts of money. They are more likely to spend it before it accumulates, or to not accumulate it at all due to their choices.
