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.
Schiff was right, but then he recommended his clients buy foreign currencies, foreign stocks and commodities. They were crushed when the dollar soared and commodities tanked.
