Migration and the NHS

With the threat of reduced migration to the UK I see that the NHS is saying that we will not have enough medical staff. Am I the only person that believes that is wrong to base our recruitment policy on "stealing" staff from other countries? Particularly when many of the staff come from developing countries who need the staff to look after their own populations. 
If people wish to move to another country that is up to them, but to base recruitment policies on using migrant labour seems wrong. We should train more people in the UK - and if NHS staff were paid a decent wage then maybe there would not be a retention issue
