The right to collectively bargain to change the terms and conditions of daily work promises social and legal equality to workers. The right to eat anywhere they wanted and to vote for the candidates of their choice promised social and legal equality to African Americans in the Apartheid South. The right to marry the person they love, regardless of gender, promises social and legal equality to gay and lesbian people. While authoritarian populist movements of the right usually seek to restore and retain privileges for some citizens at the expense of those less fortunate, successful social movements from the left are logical extensions of the bedrock birthrights of the American experiment to more and more people. “Justice for us,” says the Right. “Justice for all”, says the Left.
