We have reached a crossroads in our history. For all the achievements and riches of our time, the world has never been so unequal or more unjust. A century ago, at the time of the First World War, the richest 20% of the world’s population earned eleven times more than the poorest 20%. By the end of the twentieth century they earned seventy-four times as much. Today, despite seven decades of international development, three decades of the Washington Consensus, and a decade and a half of Millennium Development Goals, our world is even more divided among the haves, the have-nots, and—as President George W. Bush once quipped in an after-dinner speech—the have-mores.
