There are electronics built in other countries as well such as Malaysia, Vietnam, S.Korea, Taiwan etc....keep in mind this is a duty on the FOB or Ex-Factory value (depending on terms). So say a $200 projector at ex-factory pricing now has a 25% duty of $50....then add back in international freight costs, US import and distribution, markup etc and it's not a 25% increase on the product price, albeit a significant expense, it will become just another cost factor. As to who moved factories over, pretty much same crowd of saber rattlers that the drumpf represents.....heck the drumpf was one of 'em, he had his clothing (and his daughter as well) had their goods made in China and elsewhere....kinda hard to reverse the last 40 years or so of international business practices and politics due a change in heart by the republicans who very much participated in the whole thing.
