If you want me to be honest your all kidding yourselves if you you think that the UK is not racist, there is a long history of it that goes back longer than any of us have been alive
Partially true but Britain still treats foriegners in britain better than a lot of countries do! As for the working class/man etc.... I can't think of any goverment in history that has been overly concerned about the 'average man in the street', even if they started out with good intentions 'power' becomes the ultimate aim!
MRMOM = Just stop worrying and debating, it's all irrelevant, you have a chance to broaden your horions and make a bit of money (good exchange rate at moment) grab the chance! My first teaching job was in Iraq in the middle of a war, everybody thought it would be a disaster(valid concerns on their part) guess what? had a wonderful time which I would not have missed for anything!!!! Yeah sure there were a few scary moments and I saw things that were upsetting but I did choose to go there in wartime! Life is what you make it though and overall it was a good experience.
Most people you meet will look at you not your nationality, up to you how you deal with your life here. My MR is polish and despite the economic situation has carved a life out for himself and we live in an area with very few jobs! There is some prejudice here but 99% of people are okay, if they have problems they keep it to themselves. Biggest problem he has faced has been one or two other poles and if he had been a little less niave about people he wouldn't have met those few problems! Jump in get your ticket and stop thinking so much and live your life!
