But as I've said the question is not how much immigration do we allow, it is whether we choose to manage the process. Do we take steps to make immigrants part of the community, or are we content to let "community leaders" assume responsibility and allow the formation of ghettoes? How is housing to be allocated? Should non-union scab immigrants be able to offer to work for less money than existing workforces? No immigration controls implies, whether you like it or not, a free for all when in fact just pretending that large movements of labour will create no social problems which have to be addressed is fantasy.
When I say the left are not looking honestly about the issue it is because they are wedded to a concept of anti racism that is liberal and indeed anti socialist, which has had the effect of structuring communities of ethnic/religious rather than class lines. Because this makes for muddled and confused thinking it is dishonest. And in the name of anti racism they support a system which is damaging to workers of all backgrounds and colours.
