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.
If a trading bloc abandons the USD, that means they are less interested in trading with the US. Slapping a tariff in them means that they will be even less interested.
Are you seriously saying that the capitalists from BRICS countries are interested in justice, fairness, and cancelling slave owners as opposed to their own economic self interest while jostling for position with western capitalists about who should be higher in the pecking order if exploiting the global working class? Because if you're serious about that, I would love to sell you some magic beans in exchange for your cow.
