JEFF JACOBY: Let millionaire ex-presidents pay for themselves. “For all their poor-mouthing about being ‘dead broke’ and needing to ‘pay our bills,’ the Clintons’ income puts them well within the top one-tenth of 1 percent of all Americans. So why, pray, should taxpayers be giving Bill Clinton an allowance that amounts to another million dollars a year? Indeed, considering that every living past president is a multimillionaire, why should taxpayers have to fund an allowance for any of them?”
