Once or twice they did it without killing them. Usually they accused them of treason, tortured a few of their slaves into revealing things they had said and then offed them. Sometimes the family as well. Some were just exiled.
The French did it. And the Russians. It's standard practice.
I read about one very rich American who keeps a hobo's kit in his wardrobe in case he might need to mix in with hoi polloi. But their hands give them away.
I get the impression that you lefties need the rich as a rage-sink to prevent you turning on each other.
All those poor folks who voted for Mr Obama to get a "change" have been sorely disappointed.
