I was interested by the idea that artists working in a totalitarian dictatorship or tsarist autocracy are secretly and slightly shamefully envied by artists who work in freedom. They have the gratification of intense interest: the authorities want to put them in jail while there are younger readers for whom what they write is pure oxygen.
The new industries are brainy industries and so-called knowledge workers tend to like to be near other people who are the same. Think of the City of Hollywood. People cluster. This means you have winning regions such as London and Cambridge and losing regions. The people who want to be top lawyers in Sunderland are hoovered up by London.
