He has mistaken having a lot of money for having leadership talent or any useful skill that would be valuable in a situation where infrastructure has completely collapsed and fiat currency is worthless. He is not physically strong, he doesn’t inspire people to follow him, he doesn’t know how to find and prepare food, how to source water, how to build shelter, how to make fire…
