Sixty percent of Americans cannot afford a basic quality of life on their income in the US [1] [2]. They cannot "choose to invest in tech companies." They barely have enough cashflow to survive, let alone seek exposure to securities. They need their wages to go up, full stop. A stronger currency is actually a curse, not a benefit, for the American people. If the US cannot borrow inexpensively anymore due to currency weakness, it would rein in tax cuts for the wealthy [3] and spending almost $1T/year (and roughly the same for debt service) on a military unnecessarily [4] funded with debt. It would also make US exports more attractive.
Amazon, Citi, JP Morgan Chase, FAANG, Walmart, Tesla, Oracle and the other usual suspects will be fine if the H-1B program is materially impaired [5] [6].
Most Americans are not benefiting from this system, and so, there is little value in protecting it in my opinion. If another country or company invents the next big thing, copy it. "You can just do things." China has almost mastered reusable space vehicles, for example, no SpaceX required. India can use Zoho instead of Microsoft today if they wish [7] (and probably should).
