Ok then. A solution would be to say that trainee doctors sign a contract to say that they will work exclusively in the NHS for a period of, say, ten years, after graduating, and if they leave either the NHS or take their expertise elsewhere, they pay back all of the subsidy (estimated at £200,000 on top of the money paid by the students themselves) that they have had to pay for their education.
Figures from 2016, so they will have increased
This system works when people have their education subsidised by the armed forces, for instance, and it could be extended to medics, as, I believe, was suggested by Jeremy Hunt at some point.
It is rarely that I am to be found quoting Conservative policy with any sort of approval, but it does seem to me unreasonable that the taxpayer should pay so much towards educating each doctor in the system, only to have them not only, as you point out, leave in their droves to take that expertise elsewhere, but also to spend a chunk of their time whist they are here seeing private patients in NHS hospitals, and in lecturing the next generation of medics at grossly inflated Clinical Lecturer rates, both of which are 'nice little earners'.
If doctors still insist upon leaving before they have repaid their subsidies, at least there would be some money in the kitty to train more, or to invest in other areas of the NHS.
I am not a complainer, incidentally. I can see how telephone consultations can sometimes be useful, and have sometimes found them more convenient than face to face appointments. At other times, however (eg speaking to hospital consultants about concerns that can not be properly assessed over the phone) I find the system unsatisfactory, so do not think it should be a one size fits all approach.
I can also well imagine that the default telephone appointment will result in many people not being able to seek advice or medical help, however, if they are unable to be guaranteed a confidential consultation, or to take a call at a specified time so that they can make arrangements to be somewhere on their own - a point which you seem unable to acknowledge, much less answer. A pregnant schoolgirl, a young mother with gynaecological problems and children under her feet, someone in a busy office, a schoolteacher, a bus driver, a woman with a controlling husband or father who wants to discuss a personal matter - all of these people and more might find it impossible to speak privately to a GP outside of a surgery.
And you are not the only person on here to know people in the medical profession, you know? I'm sure that many other posters do too, and that not all medics feel the same the ones you quote. I know doctors who bemoan the passing of the old 'family doctor' system, and say that they would much prefer to see their patients and get to know them, rather then read emails or online forms from 'service users' and then pass them to nurses or other medical specialists. In fact, I know people who say that it is this - the erosion of job satisfaction - that is making people want to leave the profession that they used to love.
As in any profession, I am sure that there will be any number of different points of view amongst practitioners, but please don't assume that just because you have pointed something out that we should all take it as gospel.
