Society is made by men who live in monogamy. They work hard for their wife and kids. Take that away, and they stop working hard and society begins to fall apart. It's all very simple. The mistake is to assume that women are inherently attracted to men and desire monogamy, which they don't. That's why men invented law. That has been taken away from us in the last several decades, and now more and more people are beginning to experience its effects.
