[Barry the Sprout]

Just so you know there is no conclusive empirical evidence that public sector workers are more inefficient than private sector ones - some studies go one way and some the other, which leads me to beleive at least that it depends on the situation, not the nature of ownership of the enterprise in question. Also modelling Bureaucrats behaviour is notoriously difficult - there is an entire field of political theory devoted to it. Suffice to say its very hard to consistently model them as doing as little as possible and getting as much money as possible - most empirical data seem to suggest they also value prestige and even (shock, horror) pride in their work, as extremely important. By empirical data I don't mean simply what bureaucrats tell us but what is inferred from systematic study of their behaviour.
