I’m not sure GDP is a reliable national wealth indicator in countries with very high levels of inequality and cost of living. Certainly not as a comparator. Plenty to google on that too. This isn’t a criticism of your point - more that we need a better set or metrics to evaluate “wealth”.
Specific breakdowns are harder to find, but top of line numbers are pretty easy to find in a minute on Google: https://datacommons.org/tools/timeline#place=country%2FUSA%2...
