Close the borders to trade?
No, just disallow American corporations to outsource labor and create false offshore headquarters for the purpose of dodging taxes. If a Chinese company makes something in China and sells to an American buyer, that's "Trade." When an American company distributes and sells it's product in America, does it's manufacturing in China, and has a "Corporate Headquarters" in the Caymen Islands, yet all executives and majority shareholders live Stateside - That's tax evasion (albeit, perfectly legal tax evasion for the time being).
Toyota, Honda, Kia, and soon Mercedes Benz, and others, do or will manufacture in the US and will not pay certain taxes to their "home" countries as a result.
They employ many Americans.
You want that to stop, as well?
If it stopped across the board, we win. Our trade deficit is about $800 Billion per year. But no, again you're talking about something different. If they owe taxes to Japan, Germany, et al, but employ Americans, then the payroll and American income taxes are written off of their books in their respective country, yes. But if their HQ is in the Sierra Leone or some shit like that, and they're using such HQ as a tax shelter like so many American companies, that's Germany's or Japan's problem. As a matter of an educated guess, I'm guessing EU countries already don't allow such shenanigans to take place.
During the 1960's those with a college degree in my suburb was at 85%. Even post-grad was over 25%. Why? Many professors at both the suburban university and from Loyola Medical Center doctors lived there. There was also a hospital in the suburb, the doctors from there too live in town.
