Trump’s faulty trade math may not make America greater, or richer

By U.S. President Donald Trump’s math, renegotiating the North American Free Trade Agreement and other deals will largely pay for the massive tax cuts his cabinet laid out earlier in the week. He is likely off by a factor of close to 10 - or more - according to trade and tax economists who say it does not make sense to think of the world in the two-dimensional, money-in-my-pocket or money-in-yours way that Trump did in a Thursday interview with Reuters.
