If you just deploy the guillotines, then new rich people will crop right back up. You gotta change the underlying system so that the situation where rich people rule over others is impossible.
I've wanted to start a "guillotine society" for years... Just make little guillotines and leave them outside the corrupt rich people's homes and businesses... Not necessarily a threat, just a reminder.
Also for shills that support the corrupt super rich... Spray then with watered down honey and then blow feathers all over them... Good old tar and feathering but without burning their skin off
