We are still living in the long 20th century. We are stuck with its redundant technologies: the internal combustion engine, thermal power plants, factory farms. We are stuck with its redundant politics: unfair electoral systems, their capture by funders and lobbyists, the failure to temper representation with real participation.
And we are stuck with its redundant economics: neoliberalism, and the Keynesianism still proposed by its opponents. While the latter system worked very well for 30 years or more, it is hard to see how it can take us through this century, not least because the growth it seeks to sustain smacks headlong into the environmental crisis.
Sustained economic growth on a planet that is not growing means crashing through environmental limits: this is what we are witnessing, worldwide, today. A recent paper in Nature puts our current chances of keeping global heating to less than 1.5C at just 1%, and less than 2C at only 5%. Why? Because while the carbon intensity of economic activity is expected to decline by 1.9% a year, global per capita GDP is expected to grow by 1.8%. Almost all investment in renewables and efficiency is cancelled out. The index that was supposed to measure our prosperity, instead measures our progress towards ruin.
