It's really all simple. It comes down to genetic desires, and the fact that they outweigh what makes sense most of the time. It is completely human for what is happening to happen in a world with as much freedom that the West has, and it won't change without some kind of external pressure. In the past, religion was performing this role, whether our ancestors knew its purpose or not. Religion is at, essentially an all time low right now, and when you also mix in sexual liberation for the females, society will continue to destabilize. Exactly how it ends up is anyone's guess, as this age is also different in other ways: economically, technologically, etc. There are several things that could happen, but ultimately, it doesn't matter. The takeaway of this situation for anyone with enough IQ to see it is that even when educated, humans still do not understand each other nor themselves, and cannot suppress their desires in order to maintain any kind of social cohesion. It's not like it was really a question, given history, but people don't learn history either. So here it is again, history, popping its head up as an in your face reminder that both humans were crap and still are, even with education.
