It’s been a long, cold winter already for Occupy Wall Street, the protest movement that burst onto the scene in September to focus national attention on income inequality and the perceived greed of the rich and powerful. Police have cleared the signature “Occupy” encampments in New York, Los Angeles, Oakland and other major cities. Cold weather, and perhaps protest fatigue, have weakened the handful of camps that remain around the country. The lack of a coherent set of demands has made it difficult for the young movement to affect policy or otherwise score victories that might keep recruits coming.
