Let's take a momentary look at the contradictions in the above statement--I will spend 10% (or some such figure) more for imports, as I pay the tariff to the government, and I will pay 10% (or some such figure) to the domestic company, as some form of a subsidy. It's all about saving those high-paying jobs, I know . . . so spare me the sob story.
No, you won't buy the same item twice both as an import and from a domestic company. You won't double pay.
You will either pay the tariff or you will pay the cost of unemployed Americans through taxes. If you are American, you are already paying the latter. I'd rather be paying the former.
