Likewise it is unhelpful to say the least that the left talks about immigration as though it were problem-free. To acknowledge this does not make me anti-immigration (I'm second generation immigrant myself) but prepared to use my eyes and ears.
The best case in point were the residents of the sighthill flats in Glasgow. They were talked about by left and establishment alike as though they were bigots to a man and woman. Yet on the rare occassions that anyone bothered to visit and speak to them they said fairly clearly their objection was not to the asylum seekers themselves but to the fact they were, as they saw it, jumping the queue in getting stuff for their flats that the residents had been waiting for. Much of the comment in the liberal Scottish media was about how awful it was for these poor noble refugees to have to live alongside the scheme scruff.
Any large scale shift in population is going to have a social consequence. When immigrants are housed in communities which are both deprived and have severe social problems to begin with there is a strong likelihood of trouble. It is no good descending on these communities, ignoring their difficulties and loftily informing them that "refugees are welcome here."
This is not to say the working class are de facto racist. Far from it. The class which has absorbed the greatest deal of immigration, which sees the most mixed marriages and which culturally has absorbed immigrants the most (genuinely, as opposed to gap year students wearing "ethnic" gear) is the working class.
If the left is going to talk about immigration I would like to see it talking about matching patterns of immigration with resources, facilitating integration and giving communites genuine control of themselves rather than placing them at the mercy of a middle class bureaucracy which knows best. Otherwise they will have no credibility, among immigrants and non immigrants alike.
