The discussion today genuinely is worth noticing. It's about the reasons for, and likely consequences of, the "Airpocalypse" that is now evident through so many big Chinese cities. For reference: That's our old neighborhood in Beijing, in a picture shot from a 30th floor window last week.
As I argued last month -- here, here, and here -- the nearly unendurable conditions that Chinese growth has brought to many Chinese people represent a kind of challenge that the system and its leaders have not reckoned with before. Apart, of course, from the effects on the rest of the world. I think you'll find this discussion valuable and clarifying, if not exactly encouraging. (I have a cameo entry at the end, saying essentially what I've just said here.)
