You have some good points here. Although I wouldn't say "survival of the fittest" at least not in the system that is now coming to an end. It is more like survival of the most brutal and barbaric regimes who do anything for resources and control.

Look at the past 200-250 years. The colonizers who had their economies thrive (specially after WW2 where they destroyed the rest of the world) didn't thrive because they were the "fittest". They thrived because they were the most barbaric and slaughtered everyone else to steal their resources.

These principles in the West are not different today either. We are watching the genocide West is committing in Gaza live with HD quality every day and it is all over resources and control so that they can "survive".
