Making good money is necessary in the USA for one to feel free, without it you don't have freedom since almost everything in the USA revolves around money. When you experience freedom even from the need of making good money while still having a decent life you'll know true freedom.
Other parts of the developed world can deliver that, consuming is not the point after a certain level of comfort, more and bigger doesn't translate to a better life, it's just that in the USA it does.
You can live a very fulfilling life without having to worry about making more money to buy another car, to save for your kids' education, to save for medical emergencies, to access cultural experiences, etc. It's just a very different way of living, unfortunately Americans have been turned into hyperconsumers, your whole economy is designed around that idea and so the thought that life is more than purchases feels alien.
Number 2, Americans have the most spending money on average compared to any other country in the world.
Number 3, the most important technology and cultural advancements come out of the US; the US is where its happening—in a city like New York you can get the best of anything in the world, and then some.
So no, Americans who make a lot of money live the best lives, and never want to leave. It takes some cahunas and some wits to make it in the US, not everyone can cut it.
