Yes, I did mean in the ideal sense, there is a functional purpose for raising the prices of foreign goods IF there is a domestic alternative you wish to boost or expand. But the mechanism for the benefit, IF(big if) there is one, is the increase in price. Tariff = ideally targetted price increases. Saying tariffs might raise prices is like saying stabbing you might wound you. I might have a good reason for wounding you, I might not, but the wounding will happen as a direct consequences of my stabbing you, regardless.
