We might as well call it: The American left is dead. Faced with the greatest crisis of capitalism in almost a century, the left has mounted no effective mass protests, inspired no significant uprisings, spawned no major institutions or policy revolutions. In Wisconsin, labor unions lost their greatest public battle since Ronald Reagan’s showdown with air traffic controllers. In the midterm elections, the Tea Party, not the left, took advantage of economic discontent to upend the status quo. Today, the dream of socialism exists mostly as a far-right phantom, to be conjured up when Democrats dare to imply that Medicare or Social Security might serve the public good.
