One of the classic and unmistakable hallmarks of a fool is that they think they know what they are doing.
See for example: the Bush dynasty vs the typical "successful" American family. Do you know anyone benefiting from their great-grandfather's Nazi money, plus their grandfather's CIA/oil cartel black ops + presidency + Carlyle group influence trading, plus their father's presidency (and yet-to-be-proven criminal fuckery)? I don't.
