I live in London... The city tells me that old is gold... tells me to hold on to my ethnic form as there is nothing like a common global community form. The city hinges on ancient culture instead of values. It is too majestic to be assimilative in my opinion. It feels prohibitive.
New York is a different place really. A sexy conurbation... a true melting pot in this world... it tells me that communities do come together on new values and reinforces my belief in human-kind.
