I don't mind a strong public service myself, but I've seen examples of a mob mentality, where the person receiving the public service actually gets a worse service, because of complacency and lazy thinking, due to people in the public service thinking they are untouchable and also not really trying to keep updating and pioneering services.
Then enter Cameron... He knows the NHS is a key service, but he sees it hasn't been evolving, changing, and pioneeering enough to help people in the right way. So he and his ministers impose a reform exercise that they say will essentially improve service for patients and save money aswell. This pattern of public sector change in policy from government you can apply to the NHS and lots of other services.
Ed's essentially asking people to 'trust him', and that he'll be a more pertinent policy maker and decision/maker than whats on already offer, but does Ed Milliband have the character and charisma to be a Blair-style 'my way or the highway politician?
I like the One Nation conservatism/Disreali idea he's adopted, (this is the type of conservatism I agree with). The devil will be in the detail.
