These billionaire nerds got lucky, but now think themselves as natural-born leaders — as evidenced by their wealth, but they wouldn't survive the post apocalypse.

If society collapses, and you were an elite ex-special forces armed detail on a billionaire's security team, would you continue to accept their now-worthless dollars, or would you or just take a fully-stocked bunker for you and yours?

Remember there are effectively no cops or courts in this world that would stand in the way of the (former) billionaires from being demoted to farm-hand by those with the guns.
