This is the entire basis of the US, excluding Native Americans. I'm first-gen American, have only ever lived here and wholly identify as an American. My story is super common here - and its not that many generations back that most Americans were European/African/Asian as a whole. So I don't exactly understand what you mean - the power did consolidate here with the mixture of many brilliant minds across the globe, and largely has remained until a recent President has decimated our reputation.
