Krugman took questions last week on Quora, and they spanned a wide range:   -- Has Keynesian economics failed America? -- What are the causes of inequality? -- What will Trump's long-term economic legacy be? -- Why haven't wages increased alongside corporate profits? -- Would universal basic income work? -- Can Krugman refute "trickle-down" economics? -- and a whole bunch more.   In this episode, we critique Krugman's answers and offer our own.   Show notes for Ep. 166
