So if a tariff allows them( a domestic producer) to charge more for their product and they don't lose market share to one of it's domestic competitors and demand stays the same then a corporation benefits from the tariff.
You've stumbled onto the truth. Tariffs benefit favored domestic producers and benefit government while harming US consumers.
Free Traitor™ dogma 101:
Corporations do not exit as a workfare program for the USA. They can hire who they want, where they want, whenever they want in what ever country they so desire. If they operate in the USA, and they feel that wages are to high, they must be given a free hand to import as many workers as possible to get the labor down to what they think is reasonable to buy time before they ultimately move production to a third world country. They must be given free access to US markets regardless if other countries deny our products free access. They do not exist to bring the lowest cost, highest quality and best designed product, although that can happen and does happen but it is not even a priority.. Corporations exit only to maximize ROE for the stock holders.
This is the dogma that I have been fed by thbe Free Traitor™ around here for years and years.
