"I don't want to belittle what the president has done, but at the same time, there's a lot of PR going on here," said Stephen Wayne, a professor at Georgetown University's department of government. "It's one thing to pay lip service to the president. It's another to really change modes of behavior. I don't think, in the case of business, they're going to change their modes of behavior because the president asks them to."
