The man clearly has no idea what "Free trade" means.
You dont have "Free trade" when there are synthetic obstacles to trading, like tariffs and embargoes.
When there is genuine free trade, then the market will adjust to homogenize the total, resulting global market. That means other countries will rise (like his example with mexico becoming a hub for vehicle manufacture) and others will decline (like the US.)
He is literally spouting doublespeak here.
As best as I can parse documents written in idiot--
Trump laments that he cannot sell "Made in the USA" clothing, because there are no major textile mills suitable to meet his output and quality requirements in the US. They don't exist in the US, because textile mill jobs went overseas in the 70s and 80s, because it was more profitable to make those textiles overseas and ship the cloth to the US for assembly work, a la, what Levi Strauss co does. Other companies determined that doing the entire production run overseas and simply selling to American consumers was the most profitable venture. Trump is basically lamenting how he cant have his cake and eat it too.
He uses the example of "I can't find a US made television either" as an example of how this is a systemic issue. He is right on that-- it *IS* a systemic issue. The SINGLE, GREATEST attraction the US economy has to multinational corporations is our high money density in the hands of idiot consumers. Once we are tapped dry, they will go wherever the new money is, leaving the US with neither skilled laborers (because nobody hired anyone here, and skill sets died out), industry (because all the factories moved over seas) nor charity (Because frankly, we dont give money away to suckers. We take it instead.)
The US needs to wake up to this reality.
