Over the last couple of years there has been about half a million Polish and East European people come to work here.Most pubs and large shops seem to have some on their staff.The average wage in Poland is about £30($60) in London about £ 200($400).and rent about £50($100) per week.No mystery why lots of young hard working people come here to seek their fortune .And they can learn english (if they need to) for free.
