Take WeWork's Adam Neumann. "The lines between vision, bullsh*t and fraud are pretty narrow," the professor and author Scott Galloway wrote on his website No Mercy/No Malice in the fall of 2019, when WeWork postponed its initial public offering of stock. "Something is wrong," he wrote. "Something stinks. Something … Just. Doesn't. Add. Up." There were questions about how WeWork was classifying expenses and about the myriad ways in which Mr. Neumann used the company to enrich himself. He reportedly cashed out some $700 million through sales of stock and debt. (Ms. Holmes never cashed out.) But while Mr. Neumann was forced to leave the company, he never faced any allegation of criminal wrongdoing. After all, if investors suffered in part because of their own greed, unwilling to ask questions because they didn't really want to know the answers, well, whose fault was that?
