It is less about the average American worker and more about statistics. There are 1 billion Indians and Chinese each. When a few thousand of them are migrating to the US every year, you get to meet the candidates that have been pre-screened to be among the best in their respective could tries. Now since the US has better amenities, the 99th percentile Indian, probably rubs shoulders with a 95th percentile American. But even then, there are just as many 99th percentile Asians as there are 95th percentile Americans (due to population differences) If Amazon needs a person who is in the 95th percentile on Math/Analytics/CS , then at a certain point they run out of Americans. They then have 2 options. Either hire 99th percentile Indians or lower the hiring bar. IMO, the US has managed to stay on top in the tech through shameless poaching of top talent across the world. (Among other things) Letting go of this talent, across the board, might lead to short term citizen job growth, but may cause long term job loss as companies setup base elsewhere, in search of talent or competition gets stiffer.
