I can see that - I guess it's his approach. I'm wary of anyone claiming to know the right answer based on little actual experience, especially when those claims are backed up by nothing more than statements like "we must do this or that,etc." If it was just some dude's blog post, it would be one thing but it's a post on Harvard's website so I'd hope for a little more rigor.

*Edit: I recommend a book called Deep Economy that does a much better job of explaining why these were good ideas worth investigating.
