I would prefer she keep MILES away from this guy. Nobody is right all the time, but Laffer was so spectacularly wrong when he bet a penny that Peter Schiff was wrong when he predicted the real estate collapse in 2006/2007. If you haven't seen it, check out this YouTube between 53 seconds and 1:53 of the 8-minute montage.
A month or so ago I saw Laffer on a talk show promoting his latest book and when the host asked him about that miscall, he said, "That's why I only bet a penny". Too glib for my taste, for he reality he admits he's full of crap.
