Import tariff do not slow growth and are far far far superior to the income tax. Their only fault is the can be inflationary which dissipates as domestic suppliers kick in. Nobody is listening to your illogical free Traitor™ lies anymore.
Anyone with half a brain can see that a tariff is a tax.
A tax is not a source of economic growth and never can be.
You don’t get to make up your own economics, much as you are dependent on that.
Tariffs were notorious for the potential for bribery of government officials. Who would pay them more: the iron and steel makers who profit from the exclusion of foreign steel or the Railroads who lose because the steel is higher? Steel was a major input to railroads. This is only one of many instances.
There is also the potential for disparities of impact on the different states.
