There is significant income mobility in the US, which is why "the one-percent" discourse consistently fails to resonate with Americans. When 73% of Americans have spent at least a year earning a top 20% income [0], focusing on the inherited wealth of others comes off as whining. As long people feel that the pie grows, and that they can move themselves forward, these observations are at best statistical curiosities. They feel very much of a piece with the deboonkers on Twitter who tell the truck owner/operator facing 50% higher gas prices that technically there's no recession.
