Author here. Noticed a lot of traffic from this post - so thanks. Thanks especially for all these thoughtful comments. Just dropping in to say I appreciate the attention - and am grateful that most posters here don't seem to mind that I'm unable to draw hard conclusions in my original article. I also like the posts here that point towards the fact that atomisation maybe has had something to do with things (as well as the hardening of inequalities and etc.) Interesting! Perhaps it was more possible to share jokes in 2003 than it is now? (The concept that jokes either punch up or punch down seems an indication of that... Feels quite recent to me. And What if the intention isn't to hit anyone, really, just to make each other laugh?)
Anyway, to respond to a couple of other things on here. I'm not really a comedian. Sorry! I do work in the publishing industry, so while I can't prove my ideas about publishers being nervous, I would hope I have a reasonable insight and instinct.
