tariff math: no, a 30% tariff does not mean end consumer prices go up 30%

7. only some of the costs go up in proportion to the costs of the imported goods.

as noted, insurance and financing costs would go up, but the trucking costs likely wouldn't, and the advertising has little to do with the costs of the goods. so yes, some of the intervening costs are affected, but most aren't.

a further note, all this is inflationary, which forces the fed to keep interest rates higher than they otherwise would. this leads to macro effects that eventually cause an increase in all other costs, though in theory this effect should be pretty small relative to the direct effects of the tariffs themselves.
