As has been explained to you countless times before: if a domestic manufacturer cannot compete making screwdrivers if the market price is $1.00, then, when your tariff raises the market price to $1.10 (to save jobs, dontcha know), the domestic manufacturer will raise the price to $1.09 (if it is smart).
So that's the $0.09 subsidy you expect me to pay (to save jobs, dontcha know) by buying a domestic screwdriver. Well, multiply that 10% across the whole economy. Who is worried about my job because I have less money? Not you.
But the NEXT factory will be built here, not in China.
Its about the NEXT factory, tariffs would influence manufacturers considering moving offshore. In this case it is a good influence.
