Our major break came from having two devastating world wars that affected the ruling class as well, and broke the traditional wealthy feudal powers, right before an industrial boom that gave the working class a leg up never before seen in our society, to which everyone looks back fondly as that situation will never happen again (at leat not until the next violent global war/revolution).

But now, during a prolonged period of relative peace and stability, our situation is reverting back to the feudalism of lords and serfs, haves and have-nots, exactly how our civilization has always been like.

The difference is that now, instead of being the serf of a lord for food and shelter, you're the serf of a giant megacorp for employment(food) and to a giant real-estate conglomerate or a giant bank for shelter, and with a much longer life expectancy and higher standard of living.

I also disagree with your reading of history that we're regressing to the natural feudal state of humanity, which was disrupted only by the world wars. I would argue what we have seen is more like a pendular oscillation between consolidated and distributed power structures, at least over the past several hundred years.

For instance, in France and Russia, ages of elite opulence, and disregard for the well-being of the general population gave way to violent revolutions which resulted in the redistribution of power, at least nominally, toward the population. Similarly, the gilded age in the US represented a massive consolidation of wealth in a few hands, and it eventually gave way to a labor movement which put more wealth in the hands of workers.

Since the late 70's at least, the neoliberal movement has been on the march to separate labor from their power and return it to the hands of the elite. We'll see if society manages to find some kind of equilibrium, but if history is any indication it seems more likely that some breaking point will be reached, and existing power structures will be torn down in favor of new ones.
