Well it's a statement so obvious I hardly assumed it needed explaining. Have you ever thought about the practical aspect of removing billionaires? How exactly do you think it will happen? There are several methods and they're all very difficult.
Lol so no answers then? You're just hoping someone will wave their magic want and poof billionaires will be taxed away.
I've got answers. They'll take decades. If you have better answers, I'm all ears. Otherwise, ignore this folly and let's deal with climate change first, because dealing with billionaires is a lot more difficult.
