U.S. corporate boards remain overwhelmingly male, despite high-profile pushes to increase their representation of women. Today, women hold a mere 26% of board seats on the S&P 500 and 20% of those on the Russell 3000. Some see these numbers as evidence of a need for continued change — after all, women now comprise roughly 40% of students at top MBA programs and 40% of corporate managers in addition to being 50% of the population. Others have grown tired of diversity pressures and see these numbers as good enough.
