I haven’t paid that much attention to the Geithner hearings because it seemed a foregone conclusion that he would be confirmed in these weak-kneed political times. But it occurred to me today that Geithner has perfected Steve Martin’s simple advice in his routine, “How to be a Millionaire and Never Pay Taxes.” The thought seemed so obvious that I figured someone must have written on it. Sure enough, a Google search led me to this.
