Eat Is The New West
The natural order of things is for the east side of any town to be poorer. Largely historic, with prevailing winds from the West as the earth spins, the stench of the city would pervade the eastern side, while the west received fresh country breeze. It's been many years since a fresh country breeze has been spotted in London, but apart from that there was always the docks, and docks needed workers. The East End is where immigrants have arrived for hundreds of years and worked to make their homes in this country; that hasn't changed.
Things are changing, and 2012 will change more than I an imagine - but we're not there yet.
(The title "Eat is the new west" was a typo - but I've decided to leave it because I kinda like the sentiment matched with the fried chicken joint)
