As an ex NHS administrator, manag and director I have absolutely no doubt whatsoever that there are far too many in the aofrementioned positions. When I started in 1981 the Personnel department had one room on the ground floor of the maternity block. The maternity unit was moved to more modern premises and personnel, (HR to today's kids) were using every room in the old maternity unit within four years. Too many people create little empires for themselves which, in turn, create more jobs, jobs that should be taken by nursing staff and direct patient services.
Things we should prune:-
Breats implants for aspiring models whose "esteem" may suffer if they don't get them.
Cosmetic surgery for reasons of vanity, (I exclude burns victims, RTA's and the like).
Ridiculously expensive maintentance programmes for junkies.
Medical tourism.
