The views fail to recognize that US is not the only world market. More than half of Apple's revenue for example, is oversees. Exports to elsewhere in the world will be even more difficult to bring back, and harm the worldwide competitiveness of our businesses. His plan to encourage repatriation of overseas revenue for taxation is smart though.
It also overlooks the fact that we have outsourced the labor to those countries, but the US still captures most of the value. i.e. For every iPhone sold, how much money goes to Apple and how much to their suppliers? This applies to most consumer industries. The investments and trade deals mostly allow US businesses to go in and extract value from other countries, and most of the profits still come back to the top. We really don't need to capture the last mile of value.
We also can not overlook the fact that the market is already voting against US production with their wallets. The market is free to pay a premium for US made products, but clearly prefers lower cost goods.
His statements are really just feel good for a group of workers that has not adapted to the new economy.
