I think there's a huge difference between an owner of a small company and a majority owner in a major corporation or that a CEO of said major corporation. The former has little, if any, support beyond a small circle of friends, associates, and business partners. The latter has an entire tax system setup to let them fail and come up smelling like roses. Not to mention the latter has many more options and seem to be rewarded by stockholders for failing (aka golden parachute).
