Capitalism is surprisingly vulnerable. The moment of capitalism’s greatest triumph is the moment of its greatest crisis, its “moment of truth.” In fact, capitalism is not working for the vast majority of humanity that lives on the planet. Two-thirds of the world’s population have been locked out of the global economy, forced to operate outside the rule of law, they have no legal identity, no credit, no capital, and thus no way to prosper. To unlock the power of the poor is to change the world. If we fail, these people will turn against capitalism as they have turned against other failed economic systems, and that could make for a very difficult, violent time.
