When I first saw the TV commercial featuring GM Chairman Ed Whitacre telling us how pleased he is to announce that GM has paid back its government loan, I scratched my head and tried to figure out how GM came up with about $50 billion in private cash to settle the score. Actually, GM didn’t do that at all, as explained in this Washington Examiner editorial and a brilliantly easy-to-understand, brief video presentation from the folks at Reason TV.
