Hillbilly wisdom: the most obvious result of tariffs is increased cost between the trading partners. If the products are essential then the trade will continue no matter the cost. In essential cost trades, the cost of tariffs are passed through to the consumer. Who benefits?

Tariffs have enabled China to increase their market share throughout the world. We consider China as an economic adversary. When Trump imposes tariffs he is giving aid and comfort to an adversary and stealing from the American public. Increased prices increase the amount of revenue collected by the government. Where is the incentive to reduce the cost when revenue is figured as a percentage of the total cost?
