I absolutely understand the value of a country being able to produce its own materials, but one thing I’ve always question is how many people, man or woman is actually willing to work these positions once they get back to the US.
Most of why they were outsourced is because corporations can pay (or not pay) people in third world countries much less than they can Americans, but how do you convince companies to open these mines and factories in the US, and how do you convince these companies to actually play their employees first world wages? A lot of the regulations we have in place in terms of operating mines is because of corporations cutting corners, intentionally hiding the health risks until they were unavoidable and similar actions, so it’s just something I honestly can’t wait to see how it actually comes into action.
You don't volunteer to do a job, you do it in exchange for money. The reason it got sent overseas was because foreign slave labor is cheaper than domestic labor and the people making the decisions are devoid of both morals and fear of reprisal for their betrayal. Cut off the supply of slave labor and the work still needs doing, suddenly it turns out there's money to pay people. That or your empire collapses because it was never financially viable to begin with.
Most of them aren't because they've given all their executives and top brass such ridiculous salaries and bonuses that the only way for their company to remain solvent is to pay those peanuts, because those guys will never vote to reduce their pay. If asked, they would golden parachute out and leave the company in shambles.
