The American middle class, it seems to me, is looking to politicians now to satisfy a pretty basic - and urgent - level of need. Yet people in the upper middle class - with their excellent health benefits, schools, salaries, retirement plans, nannies and private afterschool programs - have journeyed so far from that level of need that, it often seems to me, they literally cannot hear what resonates with the middle class. That creates a problematic blind spot for those who write, edit or produce what comes to be known about our politicians and their policies.
