Elon Musk could have retired after making his first fortune with PayPal. He had more than enough money for a lifetime and might have devoted his remaining years to spending it. Instead, he brought his energy and enterprise to Tesla, then SpaceX, then X, and is now throwing himself with the same intensity into politics.

He is a welcome antidote to MAGA’s nativism and protectionism. A supporter of free trade and high-quality immigration, he uses X to post clips of Milton Friedman and quotations from Friedrich Hayek (placed archly alongside pictures of the beautiful Salma Hayek). Indeed, if I have a criticism, it is that he is spending too much time posting and too little time colonizing Mars. Then again, if anyone can multitask, it’s Musk.
