True, but in many cases that's not possible (I don't get to decide where my wife's iPhone is manufactured) and besides that we're tariffing Thailand, too

"Corporations can and will pass along the costs, but they can only do so until the consumer moves onward to one of their competitors."

Their competitors are also subject to tariffs. Companies don't raise prices just to be mean, they raise prices when their costs go up. Their manufacturing costs will go up, so they will have to raise prices to cover it or go out of business (just like with other taxes).

I am a registered Republican and always vote straight Republican. That doesn't mean I'm participating in the mass amnesia of basic economics that our otherwise pretty good President somehow managed to initiate in the once small government, trade-friendly Republican party

That's a deliciously ironic choice of words, my friend, considering that an iPhone manufactured in the US would cost $30,000.

I'm all for on-shoring manufacturing, but we need to obliterate the regulatory state in order to do that, not just make manufacturing overseas also prohibitively expensive
