So, I have a long response to each question, but all you really need is this. The groups you singled out as doing well are Indians and Chinese. The two most populous ethnic groups in the world are Chinese and Indians. Do you think that's a coincidence, or do you think maybe we're in a nation that's skimming from the top of two very very large populations? Now the specifics: > STEM tests at the border? You don't need STEM tests to cause this filtering effect, you just need to make immigration contingent on an employer or university wanting you to be in this country. That's what H1-B and student visas do. > why would not the same effect play out with hispanics? 1. The H1-B and student visa program isn't what brought them into the country. 2. There are fewer of them in the world. > why do 2nd and 3rd generation asians so utterly dominate STEM subjects at elite US universities that there are de-facto quotas to limit asians? STEM proficiency is inherited, and the 2nd and 3rd generation Asians are the children of 1st and 2nd generation Asians. > But most of all, how did those Indians and Chinese acquire those superior STEM skills without access to the educational resources that are given to all US citizens? Most US citizens do not get a good STEM education. Most Indians and Chinese also do not get a good STEM education, but we don't see the ones who don't.
