For more on this exact topic I
strongly recommend Plato's "The Republic". The entire book is phenomenal, but "book" (chapter) 8 [1] is something that just completely reshaped my world view. There is an occasional reference that will make you think we've genuinely made progress, like casual acceptance of slavery, but when one reads just the political timelines and transitions he speaks of, he sounds like he's describing modern times, with a bit of edgelord flair, with complete hindsight bias. But that book was written 2,400 years ago!
It was a realization that nothing, except technology, is changing. We're not entering into some scary unknown time, but just regressing to the mean. Humanity seems to be stuck on a perpetual loop, probably because we really suck at learning from the past and inevitably convince ourselves that 'this time it'll be different.' And even on those issues we do seem to have made progress on, like slavery - is it just a coincidence that slavery ended universally, after millennia of efforts, only just after the Industrial Revolution and mass urbanization which effectively obsoleted it?
On the theme of slavery, consider that we mostly don't even blink twice now a days when a country drags men off the street, separates them from their family, puts a gun in their hand, and throws them in a trench to kill and most likely die. Those that continue to refuse to kill not infrequently end up 'dying in training.' To say nothing of barrier troops. This is all much worse than even slavery, but we casually accept it, because it hasn't yet been obsoleted. If the role of humans in warfare is ever minimized, imagine what lovely things they'll write about our morality and hypocrisy, just as we are wont to do about the past today.

As for the chapter referenced, Ctrl+F for "And democracy has her own good" and read from there. "Drone" is a term you'll see throughout classical writings. It's a reference to drone bees who contribute nothing to a hive, but exist solely to consume and mate if they can. So it's a term that refers to everything from beggars to criminals to corrupt politicians who prefer enriching themselves and special interests over broadly socially motivated politicking. So in modern times it would include practically all politicians.
