I read the Ezra Klein article where he sniffs his own farts. It's just public-private partnership policy which has defined the Democrats since Clinton, but with a little more social welfare and climate regulation. His grand theory is "corporations are the vehicle for power in the US" + "not all corporations are aligned on all goals" = "we need to work with corporations to build a better future".

So why are Democrats jumping on it as if it's something grandiose? Because it's a new way to tut tut the nascent left by saying "it's reductionist to say capitalism is the root of all bad things."
