To play devils advocate, isn’t that how it’s always worked? Take away all of the infrastructure and if your genetics make you better than the others, you move on. Our class system is survival of the “fittest” but instead of survival it’s who gets the shiniest car, gets to eat the best food, and gets the best health outlook. You can survive at the bottom, just not nearly as well. 

“Fittest” here meaning a potential leg up due to family history, bit of intelligence, talent, presentable looks, and a bit of luck.  Nothing surprising, just a different definition from when humans were living in huts.
