>What incentive is there for corporations [...] to invest in its own people

Where does this obligation come from, especially considering most large corporations are multinational?

>The idea that a nation of 350 million people can't supply the workers needed for the US economy is nonsense.

For some jobs, a pulse is all you need. High Tech jobs are much more demanding. The US isn't producing enough engineers, this is well known. Even in universities, more than 50% of enrolled students are foreign born in STEM fields, see: https://www.insidehighered.com/quicktakes/2017/10/11/foreign...

You could say an obligation comes from the USA providing a legal framework and a market and the military force needed to dissuade others (countries, pirates, terrorists, etc.) from interfering too much.

No obligation is required however. The USA can just insist. This is what China does, notably, and China is not alone. Countries all around the world are forcing corporations to serve their people. That is kind of the point of a country, using the threat of force (prison, asset seizure, war, etc.) to serve a group of people.

Well then you should move to China, seeing as you prefer their system.
