In recent decades, income inequality in the United States has been climbing. Scholars and pundits argue about what causes the trend and how problematic it is, but they largely agree that it has happened.
But has the rise in income inequality between rich and poor also been accompanied by a widening cultural distance between the two groups?

On today's show, we discuss it with Emir.
A link to the working paper is here.
