Unfortunately there is less incentive for talented and qualified people from prosperous democracies to more to the US. There is significant drama in obtaining a work visa (high sponsor administrative burden), you are tied to an employer, it is difficult for your spouse to also get a visa, etc.
So the source of high skill immigrants is countries with dictators and economic dysfunction. That used to include places like Poland, Czech Republic, Italy, etc. The first generation brings new ideas and cultural flavour, the second generation is completely American. As long as you don't have religious schools and ethnic charter schools getting state funds, integration is systematic and inevitable.
