It has nothing to do with gender equality. It has to do with economic inequality between males.<p>Economic inequality between males means more and more women are competing for a smaller supply of wealthy males.<p>Increased demand for top males leads to gender inequality as more and more women compete for a smaller pool of rich men, reducing the bargaining power of every individual woman and increasing the bargaining power of the few males who are marriage material.<p>Increased demand for top males leads to polygamy and other polygamous arrangements such as mistresses.
