What about robotic automation? I think that has eaten into a lot of the unskilled work force. I don’t think Unions or the government are at fault for that.
Having said that, I think the USA is still the number 1 manufacturer on the planet if you look up the statistics.
I think many industries such as automobiles has some manufacturers that are unionized while others are not.
I think some manufacturing is coming back to the USA as has been reported.
I am not so convinced as you.
eliminate the corporate income tax, outlaw unions, place limits on litigation and liability, and repeal the last 100 years of government laws and regulations (at the local, state and federal level) that negatively affect business and you would see an explosion of manufacturing in the US unlike the world has seen since the industrial revolution.
