Tomorrow is the deadline for filing federal income taxes. And while the tax code determines who pays and how much based on income, a new book is highlighting how it also disproportionately impacts people of color.

I recently spoke with Dorothy Brown, professor at Emory University School of Law and author of: “The Whiteness of Wealth: How the Tax System Impoverishes Black Americans and How We Can Fix It.”

Miss Brown, as we head into tax filing day, you wrote an entire book based on all the things that you uncovered when you started to go through your parents’ taxes and how really the system is designed unequally. How did it start?
