Dollar dominance is a benefit to Americans. Even individuals could borrow cheaper because the U.S. dollar was the global reserve currency. The dollar losing its value hurts this benefit. Trump’s tariffs weakened U.S. dollar dominance by losing trust in the United States as a responsible leader.
The U.S. didn’t primarily lose some manufacturing due to the strength of the dollar.
U.S. problems are worse than just Trump. There are a lot of bad political ideas on both sides.
