Well I'll miss my GP.
I'm also a doctor but work in the hospital. I can assure you that I have never seen morale amongst GPs lower. All of my friends that we were wildly jealous of 8 or so years ago are now working much much longer hours, for comparatively less money and are amazingly stressed.
Jeremy Hunt announcing that missed /delayed cancer diagnoses should result in public humiliation was quite frankly the final straw for many.
I agree, we should, look into delayed diagnosis but lots and lots of people present with vaguely suspicious symptoms. The NHS could quite frankly not cope with investigating them all. The vast majority of the time GPs call it right and investigate the right people.
In the USA (I am so fucking sick of hearing how amazing the USA is) those with money get investigated and those with money don't get much care at all. If the NHS vanishes my family will be fine but the vast majority of patients I look after will be totally and utterly buggered.
Oh and for the record I've lived with various people doing very high pressured city jobs - they have all commented that the hours I worked during training (many of my early jobs were shared with GP trainees) would have broken them - on paper we often work less but the constant chopping and changing between night and day and one job and another (junior doctors typically rotate every 6 months) and the inability to plan holiday makes it far far worse.
The conservative party are really spinning a great line about how shit the NHS is. Because believe me it is going to be a whole lot worse once it has gone.
