Inflation is a thing though. My money is worth a lot less in the US than it is in Europe. Rents are higher. Restaurants are more expensive. Food and produce in the supermarkets are more expensive. And so on.

The US has created a lot of inflation through its defense budget, things like the inflation reduction act (which added a trillion $ or so to the economy, which is ironic), etc. And people commonly take loans to buy cars, houses, etc. Which all adds to inflation. It creates a lot of money but not a lot of wealth or well being.

Which is why despite being so rich, poverty levels are substantial in the US, medical care is expensive/unaffordable, and illness is a potential bankrupting event for a lot of people. Life expectancy is low and dropping (relative to other countries). Literacy and education levels are at an all time low and obesity is a national decease associate with a class of people that don't have good access to quality produce or health care.
