NEW HAVEN – Thomas Piketty’s impressive and much-discussed book Capital in the Twenty-First Century has brought considerable attention to the problem of rising economic inequality. But it is not strong on solutions. As Piketty admits, his proposal – a progressive global tax on capital (or wealth) – “would require a very high and no doubt unrealistic level of international cooperation.”
We should not be focusing on quick solutions. The really important concern for policymakers everywhere is to prevent disasters – that is, the outlier events that matter the most. And, because inequality tends to change slowly, any disaster probably lies decades in the future.
That disaster – a return to levels of inequality not seen since the late nineteenth to early twentieth century – is amply described in Piketty’s book. In this scenario, a tiny minority becomes super-rich – not, for the most part, because they are smarter or work harder than everyone else, but because fundamental economic forces capriciously redistribute incomes.
In The New Financial Order: Risk in the 21st Century, I proposed “inequality insurance” as a way to avert disaster. Despite the similarity of their titles, my book is very different from Piketty’s. Mine openly advocates innovative scientific finance and insurance, both private and public, to reduce inequality, by quantitatively managing all of the risks that contribute to it. And I am more optimistic about my plan to prevent disastrous inequality than Piketty is about his.
