> What kind of technology enabled wealth gap in feudal society? It seems it was more about religion being used to subdue people.
I'd argue the advent of centralized currencies did more harm than any and all standing armies combined.
When you think about what a parasitical entity does in biology, you realize that simply killing a host is not evolutionary advantageous--their are 3 types of parasitism, not to be confused with the 3 types of symbiosis of which parasitism lies in.
So instead the parasite seeks to keep the host alive as long as possible in order to extract resources/life from it in order to propagate and spread itself and its DNA/RNA into Nature in order to infect other hosts and rinse and repeat.
Simply by demanding that peasants/serfs pay taxes and conduct all commerce in the coin that bares the issuers legacy has brought about so much of Human misery and perpetual serfdom that it baffles me what immense gravity their is in just the last 10,000 years since the supposed advent of Agriculture and therefore modern Society.
I've spent the last ~15 years of my life focused on this very topic, and while I have gained a great deal of insight and probably did a PhD's worth of research, it would take my entire Lifetime to really dissect all of this.
