It is the same all the way around with immigration. If it weren't generally that way, we would have a well-run immigration program that would keep all migrant workers out of the shadows, would give them full rights under the law, and would ensure fair wages, but that is not how it is, is it? This country was based on extractive labor practices and land theft. The land theft had seemingly completely receded until it seems to have achieved a potential comeback under Trump (e.g., Venezuela, Greenland? ), but extractive labor is still seen in unlivable wages and low salaries. And none of that even addresses what has been done to higher education in this country--both to the students (see the lack of funding for universities and rising tuition) and to the faculties (see adjunct professors).
So, if you are happy externalizing the cost of profits for VCs (US students and US workers will pay that price), keep supporting what you support. Just don't get confused about "dominance in tech fields" based on past immigration due to world war, famine, the fall of the Soviet Union, etc. The US has plenty of perfectly competent STEM graduates. (My guess is that you don't even have a reasonable metric to determine what 'best' means in the context of your statement IF such a determination is even possible.)
Also, how do you realistically expect to "bring the best minds in the world to the US" under Trump? You seem to be living in a fantasy world or to have stopped paying attention to everything that the Trump administration has been doing to science in the US since last year.
On a more realistic note, the biggest threat to tech dominance right now is the cloud of hype surrounding the thing that is called 'Artificial Intelligence'. It is certainly artificial but not 'intelligent'. If you want to kill people's faith that science is useful, keep pushing the currently half-baked tech that is mistakenly called 'AI' on them. If all of that is tech dominance, it won't be missed if it is lost.
