If you made a utopia you would live in it. All those lower tiered workers choose to do so. No where in the book do you see them storming the Canadian border trying to get out, or setting up their own communes. Because why would they? They are at zero risk of starvation, zero risk of being homeless, zero risk of pathogens from sewage, zero risk of any of the other horrors the bulk of humanity has dealt with in the past. Entertainment alone is so inexpensive that you could use it as housing insulation. Who the fuck wouldn't want that!?
Hey tomorrow you no longer have to work in a sheet metal factory, you get a nice house in the burbs, you get work that requires zero effort, you get a cool car, all forms of media are cheap as dirt, your wife can stay at home if she chooses, you dont have to cook if you dont want to, your 3 kids go to nice schools in safe areas, and you have enough money to go to a bar every night. Your brain and energy levels are peak so you can engage in any hobby. Oh and the only catch is you can't literally try to overthrow the government. I know, so oppressive.
You yell about the violence in the system, has their ever been a government that didn't have that? Go ahead and pick the nicest government you like on earth and ask yourself what would happen to you if you starting burning down buildings and attacking the powers-that-be.
And your comparison about slave owners demanding gratitude is just plain wrong. An abusive parent and a good parent both will say that they are a good one. No one is the villain of their own story. That is why you have to look at facts. And the fact is that those workers had more material wealth and agency compared to chattle slaves.
One thing you got right, they do hate us. I am despised in pretty much every factory I show up at, but it's fine the feeling is pretty mutual and feelings don't change facts. These places are a mess of inefficiency, waste, and poor workmanship. I have production horror stories of the union metal shops. A few months ago I came to a metal shop for an upgrade and the machinist had a recliner in the shop. Spent about 6 hours on Faceboot and listening to conservative talk radio. I swept up a bit as I was heading out and he told me that he never cleans because it isn't his job, then sat in his recliner again.
I think the ending of the book summarized the author pretty well. The luddites had no idea how to replace the society they torched. Kurt didn't have any solutions, he had complaints, and I can't do anything with actionable items.
