Economics - London and the super-rich.

Has London become a playground for the super rich? A safe haven for oligarchs and plutocrats, whilst teachers and nurses, and other normal people can´t afford to live there anymore. Professor of sociology Caroline Knowles, thinks so, and warns against the increasing gap between rich and poor in the city. She has written the book "Serious Money. Walking plutocratic London", and photographer Elin Høyland and me joined her for a stroll through the London of the super-rich.
