Why are you trying to make this about race? Clearly someone who has been here for nearly 20 decades is someone who ought to be given citizenship. But that has nothing to do with preferring to continue to bring in foreign workers rather than invest in American citizens who are struggling.

Americans make up only 4.3% of the world's population. Thus, even if we invest much more in American citizens, which we surely should, don't you think it's inevitable that progress in tech will nevertheless be driven largely by foreigners going forward? We could choose not to let it happen on American soil, which some of the comments in this thread seem to be advocating, but I fail to see how such a policy would benefit Americans.

A large population doesn't predict success in tech because there is no reason to suppose the proceeds of tech research will be evenly distributed per capita.

There is first the network effect, uneven distribution of financial resources, uneven availability of educational resources, the high number of societies that don't value individuality nor deviation from tradition and the norm.

Why? It's not like Americans were a much bigger share of the world population in the past.
