The irony is unsatisfaction is rewarded. You can earn millions of dollars with making the world less beautifull, by selling people bad loanes or artificially keeping medicine prices high.
I don't know if people can learn to have enough, or 'the system' must enforce it a little bit.
The equating of money and utility (in the economic sense) happens very quickly in micro economics 101, and then you spend the rest of the class speaking about money. But that is just because utility is very hard to track or reason about.
Plenty of folks living good lives without being flashy about it.
A lack of satisfaction can also materialize in positive ways that do improve the world. This drive is innately human and is what led us to agriculture, medicine, technology, and to wherever else we're going to go.
Anyone knows the word for 'never having enough money, land or power and aquiring it at the cost of others'?
