Thank you for mentioning it. I have been through his Financial Peace University seminars three times, studying psychology.
P.S. I recall some geopolitical social engineering. I was on the FPU forums and slipped in a couple posts how David promoted selling all your gold and silver to his friend on the side of the stage there. Many people did so on the advice that this was very wise, to sell your gold and use the money to get out of debt. But this was while gold was in a soaring price Spot. So these people lost all that profit, that David's friend (we can easily presume) gained.
The forums shut down. A few years later they were back up though.
