On Social media, after the SpaceX IPO numbers are flying in the air. Millionaires... Elon Musk's $1 Trillion net worth. The whole thing is decimated to $ numbers.
Whereas people at that level can't care less about the $ attached to it for the reason below. Probably their utility function peaked and trending lower.
The satisfaction is from some thing else. The drive to achieve...
In ECON 101 we are thought the marginal utility function.
The marginal utility function measures the extra satisfaction gained from consuming one additional unit of a good or service. In economics, it represents the first derivative of the Total Utility (TU) function with respect to the quantity consumed (Q)
Diminishing Marginal Utility
Most economic models follow the Law of Diminishing Marginal Utility. This dictates that while the first unit of an item gives a high level of satisfaction, each subsequent unit provides less and less additional joy. For example, the first sip of cold water on a hot day is incredibly satisfying, but the tenth sip provides far less benefit.
