As the United States has suddenly pulled out of the Trans-Pacific Partnership, it is a good time to review the last, important trade deal of similar scale, NAFTA.
As this chart shows, trade deficit with Mexico and Canada increased from USD$17.0 to $177.2 billion. According to this paper by Robert E. Scott, NAFTA has indirectly displaced upwards of one million jobs from the United States.
The question that remains is whether sudden withdrawal from TPP will reverse the flow of jobs, or simply ignite a trade war.
