Enron. Wells Fargo. Volkswagen. It’s hard for good, ethical people to imagine how these meltdowns could possibly happen. We assume it’s only the Ken Lays and Bernie Madoffs of the world who will cheat people. But what about the ordinary engineers, managers, and employees who designed cars to cheat automotive pollution controls or set up bank accounts without customers’ permission? We tell ourselves that we would never do those things. And, in truth, most of us won’t cook the books, steal from customers, or take that bribe.
