22. John P. Mackey and Walter E. Robb,
Co-CEOs, Whole Foods Market

Mackey launched the first Whole Foods store in Austin in 1980 and has since built the country's leading natural and organic food vendor. He's an outspoken CEO, unafraid of wading into contro­versial subjects like Obamacare (he's against). For the past few years Mackey has shared the CEO job with Robb, a keen or­ganic food advocate who joined the company in 1991. Their division of labor seems to be work­ing: Profits are up 44.4% over the past year.
