I agree with sqad that NHS consultants are are under stress as never before. They are under the control of managers who can make life miserable for them in many ways ranging from delaying, say, a replacement secretary, to suspending them, referring them to the GMC, with no redress for groundless suspension/referral.
"You are no longer the servant of the people who come to you for help or of the population from which they come, or answerable to the ideals of your profession. Your immediate loyalty is to a body whose primary oath is "First Balance Your Books" or First Meet Your Targets" or "First Satisfy Your Shareholders"

No.2 son is in Australia where as a registrar he gets paid more than his brother who is a NHS consultant, so better pay does come into it , but a much better working environment is perhaps a more important factor in UK medical emigration.
I disagree that in this country that doctors'salaries are "unreasonably elevated" and "unsustainable".
The facts show that UK specialists earn pretty much close to the OECD average - 2.6 times the average wage. I see that in Ireland they earn 4.5 times the average wage.

My views are also based on my own experiences - anecdotal and otherwise..
