Why Trump wants to renegotiate NAFTA:

Turns out that NAFTA is the chief cause for the decline and fall of our manufacturing enterprise.  Since its signing,  the United States has lost 6 million manufacturing jobs.  Trump is our first president since NAFTA to show concern for the working class,  and I am including Clinton,  GW Bush and Barack "I wannabee Somebody" Obama.  After all,  it is not fair that the United States be the leader of free enterprise,  so the progressives gave our jobs away,  just to be fair.
