if trump were serious he would be willing to sacrifice a bit of profit to make all his products in America. Heck trump could be innovative and start businesses that make his products in the US. Many states would make him deals where that would benefit them both.
I know of a designer whose apparel is shown on QVC when her clothes are made in the US she mentions it because she knows customers like that. It will only benefit trump to stop outsourcing his products.
Trump’s primary business is real estate, not sewing factories . Apparel requires a lot of specialized knowledge like any other industry. Most brands are subcontracted now and I doubt Trump clothing is of a volume to support dedicated factories.
