Whenever he says you don't understand anything about economics what he actually means is you do, that's why whenever anyone asks any question that shows they know what they're talking about and he doesn't then he calls them stupid and refuses to answer. He's lost interest in responding to you because he knows you're not a mark or a 'sucker'.

He'll never say 'why' you're wrong, because he can't. He is actually well aware he is wrong.

You'll notice in this thread he tries to push anyone critical into communicating with him via email. This is so he can can pretend to have an answer in public, but not make a fool of himself by actually giving one. What he doesn't realise is it's already way past that and he's not even doing damage control anymore, he's just digging himself a bigger hole.
