This is a tiny bit of something I've been noodling over since the London riots. Artists and scientists are luxury goods. In the short- and medium-term, you don't need them to live. You only buy luxury goods when you've got plenty of disposable income and you're secure in the future. I think the London riots, in the context of massive social spending in England, are symptomatic of societal poverty and disorder.
I would further suggest that by fighting traditional societal mores, artists and academics in general* have cultivated the very conditions that threaten themselves. They've fought to overturn and subvert traditional institutions like churches and societal mores and have replaced them with the relativism that led to interviews like this.
Buildings burned, businesses ruined and no remorse. Where will the artists and academics get their money now?
Related and a very good read: Our Precentor of Measurements has a short post and a link to an excellent essay on being a Superversive. It was quite provocative and clarified things for me.
* - Originally I had called out scientists, but I think this is unfair. When I think about my own alma mater, I'm not sure the science and engineering departments cared a hoot about which way the societal wind was blowing.
