We didn’t stop listening to him because he is sound, we stopped listening because he was mostly wrong. He got the housing and banking collapse correct (but he was not the first) yet he failed miserably in telling you where to put your money instead, decoupling never happened. A dow index fund would have beat his advice, if you can’t beat the monkey, your words begin to sound like charlie brown’s teacher to me.
Now that he is running for political office, he becomes even less credible.
If I predict that the house you are in will burn down and tell you to run to your neighbors house to be safe, then both your house and the neighbors house burn down, am I genius?
