The shocking thing is as you learn about mercantilism you learn that so many rich people seem to actually believe in Mercantilism rather than Capitalism. A big part of Mercantilism was the idea that all deals have a winner and a loser, and that no financial deal can be mutually beneficial. It encourages tribalism, and ruthless cutthroat competition between countries, and it encourages really predatory financial agreements between parties. If you're making a financial transaction and know that the one party is going to be screwed over by it, you might as well screw over the other party as much as you can get away with to ensure you're the winner and not the loser.
