Our enslavement to oil has required the repression of millions of Arab people. As they shake off their bonds, so must we.

A term like capitalism is incredibly slippery, because there's such a range of different kinds of market economies.

It is our great collective misfortune that the scientific community made its decisive diagnosis of the climate threat at the precise moment when an elite minority was enjoying more unfettered political, cultural, and intellectual power than at any point since the 1920s.

We can't leave everything to the free market. In fact, climate change is, I would argue, the greatest single free-market failure. This is what happens when you don't regulate corporations and you allow them to treat the atmosphere as an open sewer.

We have not done the things that are necessary to lower emissions because those things fundamentally conflict with deregulated capitalism. ... We are stuck because the actions that would give us the best chance of averting catastrophe - and would benefit the vast majority - are extremely threatening to an elite minority that has a stranglehold over our economy, our political process, and most of our major media outlets.

Politics hates a vacuum. If it isn't filled with hope, someone will fill it with fear.

It is eminently possible to have a market-based economy that requires no such brutality and demands no such ideological purity. A free market in consumer products can coexist with free public health care, with public schools, with a large segment of the economy -- like a national oil company -- held in state hands. It's equally possible to require corporations to pay decent wages, to respect the right of workers to form unions, and for governments to tax and redistribute wealth so that the sharp inequalities that mark the corporatist state are reduced. Markets need not be fundamentalist.
