Or, you know, the future bottom line. I wonder how much these people understand that if you kill everyone or put them under serious resource strain because of environmental collapse, there's no one left to pay anything to you. How hard is that to understand? Don't pull the trigger, because yes, right now you don't have a bullet in your foot, but in a few milliseconds...
Once you are a trillionaire or getting there, personal safety can be bought even without receiving future payments.
Most of those people are old and don't care about the future. Not their problem.
