Angry chants of “Wall Street greed” interrupted former Massachusetts Gov. Mitt Romney’s opening speech at the Iowa State Fair today. During the question-and-answer portion of Romney’s presentation, a couple of left-leaning questioners wanted to know why Romney doesn’t favor raising the payroll tax to shore up Social Security and why he’d be OK with cutting Medicare benefits. Romney responded, but the questioners continued to banter with him at a high volume, prompting the former governor to say, “If you want to speak, you can speak. But right now, it’s my turn.”

Ultimately, Romney handled himself well — and was right to say eliminating the payroll tax cap would, in fact, amount to a tax increase. At least the questioners are concerned about Social Security reform. But rather than suggest the tired solution of forcing some to explicitly pay more than they’ll even have hope of receiving in benefits, they might want to consider other potential solutions, like, oh, say, raising the retirement age, an easy and readily implemented improvement.
