  "The 21st century can’t be a continuation of the 20th. We’re too close to too many edges for that. In the 20th century, the market triumphed over all. It defeated communism, leveled national boundaries to trade and brought material abundance never seen before.
But the market’s triumph was accompanied by huge unpaid costs — bills that are now coming due. Of these, the most momentous are those owed to nature and the poor. The 21st century must not only pay these bills. It must, at the same time, solve two systemic problems: How can we share a crowded planet with billions of other humans, other species and ecosystems? And how can we improve the quality of life for rich and poor alike? The unbridled market can’t solve these problems alone.
It needs a counterpoise with a different calculus. The ideal counterpoise isn’t, as many thought in the 20th century, the state. It’s the commons . "
