I propose a new law. If the victim of a murder is someone who owns a fortune more than 1000x the median household income, then someone on trial for the murder can make an affirmative defense that it was ok, simply because, "he needed killin.'"
Literally, if you can convince the jury that the guy had it coming, you get off Scott free. Anyone who wants to avoid potentially being killed and having their killer escape unpunished can avoid this fate by simply not hoarding wealth over the critical threshold. Those who hoard such fortunes will just have to live with enough kindness that no one could ever convince a jury that they deserved to die. We'll end up with no billionaires or every billionaire becoming like Fred Rogers. I'll take either outcome.
