1) most of the older builders I know (well not most but a lot) moaned about the Poles initially which I found rather funny as I knew for a fact 3 of them had worked in Germany in the 1970's for months at a time because the money was better and they shared houses 3 to a room!
2) Economic migrants should be welcomed with open arms. The reason why the USA is so successful today is because the people who went over initially were poor, hungry risk takers. They chose to leave everything behind and wanted to make a success of their lives.
3) I think the 'first safe country' law on asylum seekers needs to be enforced harshly-i.e if you life was in danger and you fled, why trek all across France and try and cross the channel to the UK-smacks of them knowing we're a soft touch on scroungers.
4) Immigrant communities add a lot to the country in terms of culture, foods, music, sport etc. However I do feel that we should try and instill a sense of pride in them at being English once they are a citizen. Just look at the second names of the USA football team-all immigrant families but all immensely proud of being American.
