When you [im]pose tariffs, it is an economic fact that you lose efficiency, and domestic consumers (in this case other businesses) lose income that could be used towards investment in other areas.Could you cite some economic facts that support this claim?
And is it the interests of the consumer we should be pursuing, or the economic viability of American industries?
This is easy. If people/companies have to use more disposable income to pay for artificially high steel costs, that is an inefficient use of capital that could otherwise be directed to more efficient investments.
