I've read a lot of post-GFC literature. Much of it is timid and limited in its scope.
This one is not. I enjoyed the ex-head of the CBI and a potential head of the BoE, explaining half-way through why he is not a green anarchist. It seems at that point as if his line of argument leads him to within an inch of growing dreads and setting out onto the festival scene with a dog on a string.
In summary, the discussion of post-growth economics makes good sense, and is hard-headed, not motivated by eco-mysticism.
