I'm for giving them a choice. The guillotine or we take away their money and make them work a minimum pay position in one of their factories for the rest of their lives. I'm pretty sure they would take the guillotine after a week.
Billionaires use violence all the time to get what they want. Just because they hide behind layers of abstraction that they've set up, doesn't mean they aren't using violence.
Actually doing this would not only be immoral but just treat the symptoms of the downfalls of capitalism, not the cause. We need legislative change that has a proper social safety net, not violence LARPing.
This whole populism trend is concerning to me. I agree that some folks are more responsible than others for the problems we face today. Even so, singling out and blaming a small group of people for the problems we face, then punishing them with legislation, is not the most productive way forward. We need real, serious solutions. "Get rid of X" rarely, if ever, works.
