& it benefits Americans (even those whose families have been here for generations) tremendously. I am a “native born” American, and I’ve benefited a lot from having a whole bunch of extremely smart immigrants in my field. My physics graduate school mentor was from Ukraine, my advisor was an immigrant from China. The person who hired me out of graduate school to an aerospace/materials science job was an immigrant from the Philippines. Several of the coworkers who have best coached and mentored me were immigrants from Zimbabwe and Korea. Generally more helpful and kind to me than native-born coworkers. It is as positive sum as it gets. (although I don’t think it lasts very long past first or second generation immigrants. It’s more individual choice and family culture than anything. So the only way to keep the benefit of cherrypicking & equipping the most ambitious and brightest among the world is to continuously encourage high skilled immigration.)
