The president-elect wrote that the coalition of non-Western countries “should expect to say goodbye to selling into the wonderful U.S. Economy” if it backs a currency other than the U.S. dollar.
For those with enough wealth, it's a win-win. Either the dollar stays strong and you continue to trade assets/stocks/bonds accordingly, or it craters and you invest in cost-competitive labor on par with India and China.
In the latter case, while foreign goods are priced out of reach, a booming manufacturing sector will come in and "save the day" in states with poor worker protections/rights. The real magic trick is making sure you (the 1%) are in the room when the decisions are made to hold or fold before the general public knows anything about it.
