Michael Sandel: Why we shouldn't trust markets with our civic life

1,791,283 views


In the past three decades, says Michael Sandel, the US has drifted from a market economy to a market society; it's fair to say that an American's experience of shared civic life depends on how much money they have.

But when, in 1995, the wolves began to come back (thanks to an aggressive management program), something interesting happened: the rest of the park began to find a new, more healthful balance. In a bold thought experiment, George Monbiot imagines a wilder world in which humans work to restore the complex, lost natural food chains that once surrounded us.
