I know lots of people here say that much of what Naomi Klein and friends think about the economy is wrong, and rightly so, but there is a reason why they think what they do. I wrote a post about it recently (in the FTWD subreddit, strangely). Take a look.

Climate change is going to be really bad, and the only plausible way to stop it is to degrow, pretty much.
I think I saw a climate economist about here somewhere, so they'll probably jump in and destroy what I wrote.
