The problem with studies, is that they are always years behind the current date. The word Surplus isn't in the article. So he can talk all he wants but we are still a net importer than exporter.
Yes, I agree autos and planes are still strong. The price of auto's never go down.
But since those studies (2012-2013) the Shale Oil industry has collapsed. Caterpillar whci used to sell mining equipment to China is in the dumps. Coal has collapsed in the US. The largest Oil refiner in the US is owned by the Arabs. The TPP trade deal was signed which allows even more industries to be bought by foreigners. Ford announced they were going to build in Mexico even though somehow BMW still makes autos in South Carolina. GE sold it's appliance business to China.
