I am spending a lot of time in hospitals right now, and the many "foreigners" on the staff do not "slouch about" at all.
They are good people and dedicated workers.

I am very grateful for the care they give, though I feel guilty that we steal them from poor countries because it is cheaper than us paying to train them.

Is there room for more people to come here.
Yes.
It used to be said that every living person could physically be fitted on to the Isle of Wight.
England is already about the most densely populated country on Earth, and the population has just increased by the equivalent of another Leeds in just one year.

Obviously we have not built another Leeds, so the desperate shortage of houses, schools and hospitals gets worse every day.

Will you call me an obscene name again for this Dave?
