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.
