>There is an amount of wealth (and I think it's substantially less than a billion dollars), past which gaining more wealth won't improve your standard of living at all. That is based on a very narrow definition of standard of living. If you include the "goods" that are social status among your wealthy friends while you're on your Mega-yachts around the isle of Capri then power is itself a part of your standard of living. Standard of living should be any good or service you have access to based on your income/wealth. Those goods don't have to be material goods but can be conceptual / philosophical goods. Thus, reshaping whole industries, singlehandedly pushing the boundary on the privatization of space, etc can all be thought of as part of one's standard of living for the world's super elite.
