America, much derided by the bien pensant, has the most open system to women to achieve top performance in the largest and widest number of fields of endeavor.
From Cowen's post:
That is the new and quite interesting book by Nima Sanandaji. The main point is that there are plenty of Nordic women in politics, or on company boards, but few CEOs or senior managers. In fact the OECD country with the highest share of women as senior managers is the United States, coming in at 43 percent compared to 31 percent in the Nordics. More generally, countries with more equal gender norms do not have a higher share of women in senior management positions. Within Europe, Bulgaria does best and other than Cyprus, Denmark and Sweden do the worst in this regard.
