some of what you say there is relevent, but dismantling it, no.It is a behemoth of an institution and should have been dismantled years ago. A&E, minor complaints and procedures, GP care and geriatric care should be privatised and underwritten by insurance. Life threatening diseases, cancers, organ failures and disease should remain within a publicly funded scheme.
with a firm hand its inefficiencies can easily be controlled and yes, i would also like to see gp visits having to be paid for and for there to be less abuse of the a&e system, but geriatric care should remain free.
as someone who worked within the nhs i can say that it is the managerial side rather than the clinical side that needs reforming, clinical and auxilliary workers are dedicated people often forced to work with their hands tied and controlled by a greedy, self serving box ticking target chasing management with seemingly little understanding of life at the coal face.
