A lot of the jobs polish people do are the jobs the lazy british people sat on benefits enjoying their plasma screen tv's and holidays in spain wouldn't dream of doing. There isn't a great demand for jobs working at 4am packing boxes or the like which the polish workers will happily do.
I couldn't care less where somebody comes from if they intend to get a job or do something useful...maybe we should do a one for one scheme..if we get a foreign person coming here...we send back one of our bone idle bastards in return.
