The projections for these trade agreements are always wildly optimistic in order to get buy in.  It will be interesting to see what the US panel investigating the benefits of NAFTA come up with.. its good to see that finally we are getting reluctant agreement that trade deals dont benefit everybody..maybe we'll get a more honest assessment over time. Independent renouned economists agee that the net gain of any of these agreements is very small over a very long time but give the powerful multinational comapnies the whip hand .. which is really the whole point; protectionism for the capitalists.
