There was an interesting comment from duncanputt who says"
I'm glad this coalition government is actually talking about immigration. However, I think they're giving it a negative feel. Immigration can help boost the economy as long as only qualified foreigners come in. Not low lifes who will set up a fast food place in a working class area like most immigrants. If it wasn't for Indian doctors the NHS would have collapsed in the 1960s/70s. So immigration can be good if it's done correctly and in the right doses.
