The bunkers won’t help the rich if they are evil
Amen!
When the SHTF for real, these billionaires and powerful people will find that they really aren’t so.
They will find that the ‘help’ (bodyguards, etc.) may be less than helpful.
The rich require servants—and if they have servants, those servants will turn on them and take the bunker for themselves. Money, after all, will be worthless and loyalty can’t be bought.
