I never said they weren't. Seems to me they should necessarily increase the price of an imported product to the end user. Unless the country enslaving it's people is willing to absorb the cost of tariffs to achieve their long term goal.
So just to simplify it for my little monkey brain, Yes, tariffs are inflationary.
According to DemnSlayer, they also appear to be an inflationary revenue generating tax on the American people.
That power is exclusively the right of the Legislature. And no, Congress can't just delegate that away. That would be altering the Constitution without going through the amending process.
Otherwise a rogue could get his party in power and have them assign all former powers of the Legislature to the President thus creating a King.
No party has the right to throw away future elected representatives Constitutional powers unless they amend the Constitution by the proscribed process.
