Sometimes, we don't fully appreciate the greatness of people in public life until they step to the side, where they are more free to express ideas, influence or initiate change, and use social media to bring us on board. So it has been with economist Robert Reich, who served as Secretary of Labor in the Clinton administration. Currently teaching at UC Berkeley, he has authored 13 books. His film, Inequality for All (click link to watch the short trailer), sounds the alarm for the future of the middle class in America. Most recently, he's taken on Harvard Business School and how it needs to change the way it trains this country's future CEOs. I love his daily Facebook posts, which shine the spotlight on economic and social issues around the world. Follow him on Facebook, if you're there. Robert Reich makes economics accessible (and relevant) in the way Neil Degrasse Tyson makes astrophysics accessible. Rare, indeed.
