I see all the memes about guillotines for the rich, funny in spirit, but actually building one in the town square is not practical. They take a ton of materials, they are huge, and they do not even work reliably. Would it not make more sense to build one from metal with hydraulic pistons or something? I am not a machinist, but a more mobile unit you could wheel into a square to decapitate a few effigies seems about as effective for sending a message, and easier to remove or relocate if needed.
I’ve seen discussions about the future of automation where people speculate “what will rich people do with the general population when they’re no longer necessary to keep industry running for them?”
Opening up the “let’s just kill the people we don’t like and don’t want as part of society” box seems like a bad idea in a context like that.
