CHIEF EXECUTIVES normally relish the idea of having one of their own in the White House. When that man is Donald Trump, who will be back there after a decisive victory over his Democratic rival, Kamala Harris, on November 5th, the feelings are mixed. Some tycoons are big fans of the president-elect with big hopes for Trump 2.0—notably the wealthiest of the lot, Elon Musk. Others loathe the idea of having a convicted felon with a fondness for autocrats as the leader of the free world.
