I dont doubt future sec of states will come under pressure re health. But maybe the job won't exist... You can see the effect with the railways and the privatised utilities - they are not supposed to be under govt control but they keep on trying to get involved and coming under pressure re railways, fuel prices etc.
You have obviously had good experience of GPs. MY MIL lives in a relatively deprived area of the midlands and she has had terrible service from hers over the years. She has been living with my SIL in a much more affluent area for the last 9 months and the GPs are so much better there, you would not believe. It is, literally, like going to a different country. (But why wouldn't the best GPs choose to live and work in the nicest areas... ) Under the new system I think the better off areas will get an even better service.
Under the new model, nobody will take those tough decisions that have to be taken if you are to have a modern cost-effective health system. I used to live somewhere that had two hospitals and two A and E departments. Against opposition, one of them was, effectively, closed. As you an I know if you are to give a 21st century service and recruit the right quality consultants, someone has to make those choices. Who will do it under the new system? No-one will have the power. Takes a long time for "market forces" to close down a third rate department or hospital however you structure the market.
And post-code lottery-ism is going to go crazy with all the consortia setting their own priorities.
I cant see how the "reforms" are going to get rid of your excess managers either - maybe it will increase the admin/management load in hospitals even. Wouldn't surprise me.
