Do you remember PG essay about the PR submarine? That's more like it. Make no mistake, Jorge Paulo Lemann and the other two billionaire partners are among the best business men in the world. They got there building huge business after huge business (not like the gambler ex-billionaire Eike Batista).
So there are 3 very smart, wise (and old) guys telling these young smart folks where to go and what to do. Not micro-managing, of course, but the biggest, toughest decisions are theirs. So it is very different in autonomy and leadership from public companies CEOs. And a world of distance of Zuckerberg's owner, founder, CEO, rules-it-all role.
PS: I don't want to minimize the young guys success, I am sure they worked hard and smart and deserve their positions. Just clarifying what exactly means the "CEO role" here - according to my own personal opinion, of course.
