in 2016, just over 40% of our export net was incorporated into goods that were then imported back into the US. Adjusting the trade figures using this margin corrector, we end up with the following trade balance...
Initial figures in millions
211,848.7 Exports
270,647.2 Imports
-58,798.6 Balance
Corrected Figures
211,848.7 Exports
(270,647.2 x 60%) = 162,388.32 Imports
+ 49,460.4 Balance
WOW, we have a +49.5 MILLION DOLLAR TRADE SURPLUS with Mexico! Trump lies.
