Howard Gleckman spotted a revenue provision in President Obama’s health care package that would generate an estimated 86 percent of its revenue from tax filers reporting incomes in excess of $624,000. He’s unhappy with this Medicare tax add-on because it is less transparent (and therefore more politically acceptable) than a straightforward increase in the top income tax bracket. We agree in principle. But, hey: tax policy is made by butchers, not philosophers. We’ll settle for any reasonable tax that inches Medicare away from fiscal disaster.
