Not in my opinion, I don't do medicine and I'm not a doctor. I don't know the pay scales as such but I agree with the idea that GPs are overpaid for what they do and the main big earners should be specialists (this is probably the case anyway but also thinking about hours, quality of life etc). At the same time GP mustn't be discouraged as an option because I think they provide continuity of care, understanding of that one patient's issues and they act as preventative rather than reactive medicine. So although they don't really do any work the value they add to the NHS is considerable.
And also as the guy above me says the first salaries to cut are the supermanagers and the management consultants' fees. The former have been parachuted in by politicians to help destroy the NHS's finances, force working conditions down so staff defect to private, and force quality of care down so rich users defect to private. And the consultants have had to be brought in following the unnecessary pressure from politicians on the NHS's finances, and forced to recommend the same stuff.
If you actually get asked this question you can show your commercial awareness (wrong word, but...) by talking about the reports that doctors are going private or going abroad because the NHS doesn't pay as well.
