With Obama, I see no one who would be willing to pay him to come to their company/forum just to hear him read a speech from a teleprompter that was written by someone else. Obama simply has no value to give.
Flash back to his graduation from Harvard. As head of the Harvard Law Review, he should have had his choice of jobs clerking for US Appellate judges or even a stint at the SCOTUS. At the very least, a 6-figure salary at a prestigious Manhattan law firm. Yet Obama did not get a single offer. That should tell you something about his value.
Think Al "Lemme Tell You 'Bout Global Warming" Gore. Gore made a fortune by selling garbage to people, who desperately wanted to believe in it.
