Elon Musk | AP FREMONT, Calif. —Tesla Motors and more particularly, its owner, Elon Musk, have joined the ever-lengthening list of rich corporate moguls breaking labor law. In Musk’s case, it was with a tweet, and his Twitter account had—at the time of his offense—22.7 million followers. And his net worth was, depending on stock market gyrations week to week, between $153 billion and $180 billion, even though he took little actual pay from Tesla. Musk is traveling in fast company on labor law-breaking: Jeff Bezos, CEO of Amazon, one of the three richest people in the U.S., and the right-wing Walton clan, owners of Walmart, among many others.
