The "natural law of supply and demand", specifically, the supply side doesn't magically stop at the border of a country. If anything, protectionism is against the free market ideal. Labor is just another resources like any other, and the extreme version of free market would include free immigration.
Yes, a libertarian free market only society might not be in anyone benefits, and any regulation to limit them might have some merit. But we should really call a spade a spade.
Free trade laws don't appear out of thin ether either, it is companies that lobby politicians to create such laws -- while at the same time claiming to the public that they are inevitable. This is a distorted ideology that needs to be opposed, not just observed as if it were good or inevitable.
It seems like you're implying that supply and demand cannot exist without the libertarian free market. Supply and demand can exist in any system even ones constrained by managed economics or artificial restrictions.
A better strategy is to ensure US domination of technology development through any means possible.
Besides, it isn't like wages for tech workers are low in the US.
American tech would be a shell of what it is without foreign labour.
Israel is nascent and not very comparable, plus they do pull in a lot of global talent, germany also to a much greater extent than japan.
also, I'm not saying you can't have a 'viable' industry without importing good talent. I'm just saying it won't be as good.
In a country that valued their citizens, these companies would have to pay higher salaries as the demand increased, and as a result more people would chose this career path, thereby reaching a market equilibrium. If these companies moved jobs overseas, they would be liable for more taxes to offset the job losses, so they would be discouraged to do so. The fact that nobody talks about these simple strategies just shows that companies have done a great job to preach their message to the US government and workers.
