The Occupy Wall Street movement is driven, I believe, by the failure of two key societal functions: opportunity and accountability. We should address these imbalances through, among other things, a stronger voice for workers to boost their bargaining power and, in turn, produce a fairer distribution of productivity gains; a higher minimum wage; strong wage subsidies so adults in low-productivity jobs can earn a living wage; direct job-creation measures to put people to work (to help address infrastructure deficit); and a Federal Reserve that gives full weight to the employment side of its mandate.
