Well then ~ now I see more clearly your imaginary scenario of corporations and jobs. Yes that would leave you high and dry without work, but the product will come in from offshore locations and the services might be performed by immigrants who would work for lower wages.

http://www.city-data.com/forum/5880248-post2.html the scenario isn’t something that you have to imagine ~ it’s factual with corporations going offshore and government receiving less money and income because they are offshore and the jobs are gone as well. It’s not something that is “imagine” it’s criminal corporations that have occurred already thanks to criminal politicians and CEOs.
NAFTA killed American jobs and manufacturing.
