Depends what “can do the job” means, right? Elite tech companies try to hire the highest ability people they can. The US is not a large share of the world’s population, so even if it is massively overrepresented in top performers, the vast majority of top performers are still foreign born. Your position is that US companies should hire less impressive people because they are American. Maybe you can build a functioning search engine that way, so a 100% American-born engineering team can technically do the job, but does it end up being Google? Does it end up being competitive relative to what the immigrants who worked on it would have done in their own countries or a friendlier country?
