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 don’t know. I hear the rich are full of toxins and heavy metals.
Compost is usually used to feed vegetables, so I don’t think I would want that particular solution.
I would say it might be better to macerate and dehydrate the rich and then use the resultant rich jerky as part of a carbon barrier for depleted uranium and other hazardous radioactive wastes.
