There is an interview with a guy who owns one of the companies that makes bunkers. He described being offered a lot of money to consult with a group of billionaires. They flew him in a private jet to an undisclosed location for the meeting. They wanted to know: How do we protect ourselves and our families from the guys we hire for our security? Bunker maker told them straight up: You spend just as much money building bunkers for your security members and their families as you do for yourself and your families, otherwise they are going to take yours. They did not want to hear that and sent him on his way.
