At an event I moderated with Newkirk earlier this month at Politics and Prose Bookstore here in Washington, I asked why is such a failed business a billion-dollar business in the United States. "That was the question that prompted my journey to try to figure out why are companies spending billions of dollars on something that clearly has not moved the needle nearly enough over the past five decades," Newkirk said in the conversation that is the latest episode of "Cape Up."
