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.
There are people at the top who have the power to make things better for everyone but choose the furthest from that. They do direct harm to so many people with no accountability. To deny them of their lives would be showing them the respect that they show to others. It’s the least we could all do.
