As you know I think much of the UK's economic doldrums are caused by rubbish management; both in the sense of not being very good at it, and specifically the managerial mindset that workers are a cost to be reduced, not the organisation's key asset that needs to be invested in.
Two charts from the FT reinforce that argument (albeit only via correlation)... at the very same time that more people are mangers than workers, our productivity gains have stagnated.
