I'm sure I've been dense, but it just occurred to me why Obama thinks he can tell companies how to run their business, whether they took government money or not.
He's thinks that being president of the United States makes him the president of the president of any company. He's the boss' boss, in his mind.
That's key. Your company's org chart is incomplete, as drawn today. If you own the company or if you are CEO, you report to Barack Obama. You have to justify your stewardship of the company to him, from operations to salary.
In short, all companies are already nationalized in his mind. It's just that the legal paperwork hasn't been completed yet.
