I'm going to run this by you, and see what you think....
If we (or those of us who are old enough) were to go back thirty years and predict the future of the UK's racial politics, I doubt many of us would have predicted the present. Pre Thatcher mass unemployment there was a sort of layering of society. There was, and still is, an assertive black middle class in Brixton, and Idi Amin had gifted Leicester and parts of West London entrepeneurial Asian minorities. This isn't to generalise, but, thirty years ago we might saw the beginning of an unlayering.
All that 'fixed, fast-frozen' stuff has gone. It's true that the majority of Bengalis in East London live in comparitive poverty, but the assumptions that accompanied the layering are the preserve of the nostalgic. Poland has delivered a short sharp shock, from which 'we' will never recover. Now, this is a fantastic thing. A wonderful thing. Go back to the days when Enoch Powell was worshipped by millions, and ponder our progress. It's brilliant in the most cheesypeas kind of way.
The dilemna is encapsulated in the 'fixed, fast-frozen' thing. People have lost their points of reference. The folk in the Bradford club might be sad, but for real sadness you should see a tube train of people reading the Metro. The past is a mixed blessing. It limits you, but it also supports you. However hopeful I am about the new London, I'm damn sure that the millions who have been swept into the big diagram are saying goodbye to something precious - whether it be in Dagenham or Bucharest.
I suppose the question is this. Laying down tradition and common understanding takes a while. Will the new battalions of IT clerks emerge from their Facebook profiles with something to think about? I cling to the thought that cities are intensifiers of experience, and that experience can be shared and built on. The Metro-reading masses may yet prove me wrong.
