Elon Musk has no experience in government and lacks knowledge of our history. Yet his wealth apparently qualifies him to use chainsaw on institutions.

While Elon Musk has emerged as one of President Donald Trump's most loyal supporters—backing his policies and contributing over $300 million to his reelection campaign—the tech mogul's companies are now fearful of the unintended consequences of the administration's aggressive trade measures.

Mr. Musk is fundamentally a creature of Silicon Valley, a scene that initiated an entire revolution in power dressing. The young masters of that universe dressed down to show that they were members of a new elite — one that refused to dress like the grown-ups they were about to topple. It was the defeat of the suit by the T-shirt.
