Does history really repeat itself?

Here in Denmark there has been a debate about a high school. On the first day of school the new student were playing some games. One of the games was to see how much of their clothes they dare take off. The more they take off the more points they get for their team. The principal, he thought it was a great game as did the boys and a lot of the girls too! - The debate in the media was going back and forth, but I was thinking about the different societies of old. There where it became more and more amoral, not just unmoral, but no-morals! It was these societies that fell apart. It starts with the leaders the more amoral they become the closer thier society comes to a collapse. Many of the things that we say are modern "Free sex" and alike are nothing new at all. It was "normal" in Roman society and other ancient societies. Our so called free thinking is just old thinking.

So if history repeats itself, then we should see the
"Fall of ________" sometime in the near future. Or what?
