Why do they have to keep changing things ?

Cause the leaders keep changing direction too. Therefore its not entirely the fault of BB . You have to have leadership that is not to clever ( doesn't have its identity tied up in invention rather than completion ) and respects cleverness in the club . 
But more importantly, because somePS 's are clever and indutriuos , they have time too  to be petty.You can't cut the numbers ( unless you are a miracle worker) but you can give them something worthwhile to do. 

While we have polys that run around like skun cats thinking of ideas , we have PS who meddle with minor things casue they have been given a low horizon agenda - by default.  What do you think ?

The new millenuem will reveal the paradox of good governance - that its dependant on the quality of both the PS and the Polys . While we cultivate a low view of them both we will get what we believe them to be .

Why do bureaucracies keep growing?

Are the problems getting harder? . Surely the growth of the nanny state suggests otherwise. How much would the overall mental health of our society improve if we got rid of the people who are technically  " here to help you but don't seem to hear ".
Why does Brumby ( Victoria,  Australia)  allow so much of our money to go into TV and paper Ads which tell us how to suck eggs . The children may be in charge, ,  but Thankfully ,  not all the audience/people are children.  Or are we?
Got something to do with the fact that real leadership is tough and lonely and the bureau is a nice warm place where we get on rather than get on with that sort of job -or that sort of person ?
