No, but I agree with almost everything that Professor Manning said. The needs of the economy change, but we also need to make sure that there is an incentive or pressure on employers to use their labour more efficiently, to increase productivity and so on. If you look at a graph, you will see that productivity in the UK, apart from being well below France and Germany, has been flat for 10 years, and immigration has been several million in that period. You cannot possibly argue that immigration on its present scale is improving productivity or anything else.
It is also a key point that there is no evidence for the UK that immigration adds to GDP per head. I think there are one or two studies in the United States about Mexicans providing home assistance for computer experts, or something, but in the UK there is no such evidence. The basic pressure for large-scale immigration comes from employers who make money out of it. They are there to make money if they are able to do so.
