Hanna Rosin’s book The End of Men and the Rise of Women is well-researched and is heavily documented, but the research seems based on a fairly narrow demographic, mainly Eastern, from prestigious universities and in professions related to finance. As a result the conclusion she draws about people mainly in their 20s seems skewed. They would fit well in some HBO series but it’s hard to know if they represent the broader spectrum of America. It’s a chilling image of empowered women and lower-performing men; however, politics and boardrooms and financial insitutions are still ruled by a preponderance of men, so Rosin’s portrait is more a prediction of a big sea change than a snapshot of what actually exists right now. Still, it’s a provocative book.
