"Certainly some career choices enter into the overall gender wage gap, where women make 77 cents for every dollar a man earns, such as being more likely to work part-time, interrupt their careers to care for family members, and ending up in jobs that tend to pay less. But none of these factors can help explain the wage differentials at the very top. Even the idea that women are less aggressive in pursuing more pay and opportunities evaporates. Clearly women who climb to the top in a heavily male dominated world — women still make up less than 15 percent of CEOs at the country’s largest companies — have to be ambitious, and a recent study even found that female executives are even more ambitious than their male peers."
