The Sum of Us author and economic and social policy expert Heather McGhee talks about the economic costs of racism and why this is the moment to turn away from zero-sum thinking. “As this fast food worker named Bridget told me, as long as we're divided, we’re conquered. I began to see what I call solidarity dividends. These things that we can gain through collective action across lines of race that we simply can't do on our own. Higher wages, cleaner air, better funded schools. That's the new economic model, but we need to pursue the idea only through solidarity.” — Heather McGhee
