Neither lol. It’s simply to protect the American bourgeoisie profit margin and fulfill the lobbyist demands. Plain and simple. This is why Biden is going to get re-elected, not by giving in to the demands of the voters, but to the demands of the ruling donor class.

The other user said protectionism can be good for developing your own industries with minimal foreign interference, and that is correct, but the US is never going to re-industrialize.

In other words, if the US ruling class had wanted its subjects to enjoy cheap and environmental friendly transportation, you’d have gotten high speed rails a long time ago.
