Well, I really enjoyed that although I didn't learn much. His call for 3rd way liberal capitalism is pretty much where I have been politically. What's odd to me is that you are promoting this and I am learning about it from you rather than the other way around.
Did you note at the end where he says that if we don't "demonize" each other ? It's at 23:21. That part sounds more like something I would say.
The key to achieving the 3rd way that Haidt describes, is an open and clean information environment. How to achieve this is, in his words, a "wicked" problem.
