More than 40 years ago, I arrived in Chicago in search of an idea. I was a young man looking for purpose, who believed deeply in America, was inspired by the Civil Rights Movement, and wanted to be a part of something larger. The America I believed in was one where everyone has opportunity, everyone is seen, everyone belongs—because that was an America that had a place for me, too.
