Let's face it. Trump became a multi-billionaire through capitalism. And capitalism is the root of most of our economic problems. For example, in the documentary "The Corporation," they correctly pointed out that most corporations are psychopathic and sociopathic entities. Along with other bad things. With that being the case, is it any wonder that things are so bad? So to fix things, Trump is going to have to go against something that made him wealthy. Will he do so? I doubt it. But at least he is no Hillary.
Capitalism isn't the problem. Capitalism is the only economic system that has ever worked long term. The failure of Socialist or controlled economic systems has happened so often as to have achieved the same understood level of "water is wet" common knowledge.
Free trade with second or third world nations is not required in capitalism. In fact, it is a problem for capitalism. Trade between equals is a good thing, it establishes competition, and provides the environment necessary for a superior product. Think back to the Japanese invasion of the 1970's. The cars were small, ugly, used far less gasoline during a gas shortage than their domestic competitors, but most importantly, were reliable.
This competition meant that the domestic automakers had to improve their reliability. But the Japanese were not just chilling and relaxing knowing they had a good car. They worked on the styling, and improved on even their stellar reliability. The Americans learned from the Japanese, and the Japanese improved their products to stay competitive.
Competition in the market is what capitalism is all about. The consumer, that be us, got a wider selection of superior products in an effort to get our business.
Trade, and Capitalism can be a good thing. But when you have trade with an unequal economy, say one of the second, or third world nations. You have a serious problem. The workers in Japan can afford to buy an American Product, just as the American's can afford the Japanese products. The workers in Haiti making Levi's can't afford a pair of jeans that they make. The workers in Mexico aren't going to be buying a new car with what they make. In that case, you need tariffs to level the playing field. To protect the american worker from the unequal market.
Trade between equals, good. Trade between unequal economies, very bad for everyone.
