the strange thing is that it is happening all over Europe a skilled workers from eastern Europe, (poor) economy
are moving west, it is something people have always done, for as long as man could migrate to better pastures, it is human nature
it happened in the the early 1900 when large numbers of poor Europeans went to America,
if you have nothing ,you have nothing to lose,
Chinese have always been hard working, and uncomplaining. ( I may be wrong )but most of Americas railway were built by Chinese immigrants . It is like human osmoses people move to wealthy areas.
how you stop it or deter is a different ball game
