> the US wins wins when people move to the US, especially young, skilled people.
I personally lean towards this being true, but it is a claim that needs to be demonstrated comprehensively for your argument to hold water. It is not trivially true.
If these people have not defrauded the US then they would not know what to do with a work visa as they'd be hurrying back home as soon as they received their diploma, pulled by those strong ties and the desire to finally put the education to use at home.
But me personally, I advocate many fewer student visas.
Again, these are the most talented, most affluent minds that China has to offer. Sure, let’s have them work for the CCP rather than keeping them in the west.
What someone's labor is worth is up to the market to decide. Also those $100k are taxed out of the employer and employee's value.
On the benefits of people moving to the US: it's been widely studied and it's basic economics, immigrants bring both supply and demand, so the size of the economy grows and so the opportunities to current residents.
Take the extreme: when people leave a country or city the economy there collapses, see Detroit or the increasingly old and depopulating European countries.
Or take the extreme on who comes: fiscal studies show that even low skilled immigrants are net positive fiscally. Only very old and unskilled immigrants are a fiscal burden.
Finally, thinking that we can capture the world's economy in a bottle and live lavishly without competition is delusional. If we stop letting people build here, they will build elsewhere and without us. We are increasingly less relevant.
Imagine spending 25 years raising, educating, feeding, and clothing a person, investing over a million dollars of money and labour in them, and then they just pack their bags and leave.
Educated, skilled, young immigrants are a colossal gift to the host country, and a crippling debit on the welfare and prosperity of the country they have left.

Anyone who has ever given it more than thirty seconds of thought knows that countries become wealthy when people living in them work - and make stuff. So what do you do to improve a country's prosperity?
Obviously, in backwards-logic, you start raising barriers to people who want to do useful work in it.
(Because dealing with the systemic issues that have resulted in the country becoming prosperous not being correlated with the plurality of people in it not becoming prosperous would upset wealthy people who don't actually build anything.)
