From Econtalk:
Robert Frank of Cornell University talks with EconTalk host Russ Roberts about inequality. Is there a role for public policy in mitigating income inequality? Is such intervention justified or effective? The conversation delves into both the philosophical and empirical evidence behind differing answers to these questions. Ultimately, Frank argues for a steeply rising tax rate on consumption that would reduce disparities in consumption. This is a lively back-and-forth about a very timely topic.
