What economic downturn? McDonald’s is tearing it up financially—and this low-key CEO is responsible.

His jobs program teaches 1.7 million workers precision and discipline, not just how to crank the fryer. What’s more, few people wield more influence over the average American’s diet (“Over 99 Billion Served!”).
