The rise of populism is usually attributed by commentators to either income inequality or culture wars. We are witnessing, they argue, either the displaced anger of the 99% or the revenge of the 'deplorables' against the 'liberal elite'. They are wrong. In this forensic book, Eric Protzer and Paul Summerville argue that populism is actually a response to a profound sense that many of the world's leading economies are unfair. They show that in meritocratic countries, such as Australia, Canada, Portugal, and Japan, populism has not taken root. In contrast, the countries that have been hit by the worst populist upheavals - like the US, UK, France, and Italy - have low social mobility. The way to address populism is to restore the connection between contribution and reward and craft a politics that reclaims the reasonable grievances that drive populism while discarding its false diagnoses and toxic 'solutions'. Reclaiming Populism is a must-read for policy-makers, scholars and citizens who want to understand the crises of our age and bring disenchanted populist voters back into the fold of liberal democracy.
