After nearly 20 years on Wall Street, Chris Arnade left his high-paying career to document Americans living on the margins. Traveling all over the country, he took photographs and wrote about the America that is overlooked. Our partners at Amanpour & Company recently spoke to Arnade about his new book “Dignity: Seeking Respect in Back Row America,” in which he documents people living in poverty and addiction.
