I think it's a bit extreme, to eject people in need of treatment, if they are from overseas. There are thousands of people from this country who contribute little to the economy ( long-term unemployables, jailbirds, to name but two ) but get all the treatment they need if they fall ill. Each case should be judged on its own merits, as many plan a trip in order to get treatment, I'm sure, whereas many are not planned. Then again, it's the actions of some that will affect those overseas visitors who don't try to abuse the NHS system. It's the same in many aspects of life: you give people an inch and they take a mile. Many of the problems in our society today stem from shortsighted greed and little concern for our fellow man ( or woman ).
