I read a post about an article from Fortune magazine that lists 19 Black economists to know and celebrate. I think it is great that we celebrate the contributions of Black Americans, but when Walter Williams is left off of any list of important economists, especially Black economists, I have to question the motives of those who made the list. Williams is the John M. Olin Distinguished Professor of Economics at George Mason University and is one of the most important economists over the past thirty years. Why was he left off the Fortune list? Historically speaking, it is a disagreement that goes back about 150 years.
