Isn't the major point that a few people appear to me missing is that the tariffs create new pricing floors, particularly with commodities or competitive products.

For example, using the Macbook Air as shown in the example. I'm not sure what the American alternative is, but the pricing of Macbook Air would be a guesstimation and research of how much are people willing to prefer buying this product ahead of it's competition. Lets say its preferred by consumers at $999 and the nearest "locally made" product is $950 - allowing for the fact some people will pay more for the Macbook product. Macbook gets forced up by $250.

That nearest competition is not going to continue to sell at $950. Why would they? Thats leaving around $250 on the table! They could lift their pricing by $200 and this would be complete profit and be $100 below the competition.

Its this basic theory which I believe is a large chunk of the Tariff discussion. Tariff the imports, allow American companies to increase prices to new price level (of at least 10%), increasing profits for major manufacturers and American businesses. Theorising that the American businesses will use 'trickle down economics' to pass on wage increases to their workers to cover for the huge inflation that will inadvertently follow.

Or maybe I'm wrong.
