>>1732947we're pretty terrible at long term planning and we always want to do everything on the cheap, so we provide inaccurate cost estimates in the first case and then panic and cut the scope of projects once things go overbudget. (and since things tend to go overbudget anyway, the psychological effect is multiplied by going dramatically over the initial, unrealistic budget.)
the NHS is actually pretty cost efficient though, when you look at healthcare spending as a share of GDP in developed nations the UK comes out very well even though it's a bottomless pit for everybody.
