You just answered your question, Mark. The CEO of Facebook is a woman. The percentiles aren’t nearly as important as where women are CEOs. Yes, women make up half the population. Yes, they affect buying trends (and thinking trends) more than men. That requires influence. Being a CEO of an oil company doesn’t influence a broad percentage of the population. It’s pretty much of a closed society. Facebook, on the other hand, affects (yes, I said affects) billions of people. Tactically, Sandberg, is in a much stronger and more powerful position to affect change than the head of BP, for instance. Don’t worry about ratios. Worry about saturation. That’s where women are doing it right.
