מעשים בכל יום, Every dept in government needs to use up their funds in order to maintain the same funding and avoid cuts. They'll always look for waste spending to meet that. People who deal with govt contracts and employees hear that first hand.
The incentive structure (in all bureaucracies) is inverted. and it runs through, top to bottom.
incentive to maintain spending levels at the top, and employees aren't incentivized to work efficiently, just to keep things moving along peacefully.
unions help protect that as well, but in public sector there's no way you can remove those...
(to some extent this happens in some large corporations as well. but public sector has the added disadvantage that 'the bottom line' can't be used as a metric/motivator, when the goal isn't profit)
Find a way to flip the motivation scale, and the efficiencies will create themselves
manage to invert the incentive structure, the efficiencies will happen by themselves.
