They exist. Corporate culture starts at the top. Thats why CEO get the big bucks right?
I have worked in well run government departments and bad, ditto for private sector organisations. What made the difference was the culture. In "groups" that put group reputation ahead of short term personal gain, the better the output.
If your leaders or managers appear more interested in their personal gain and appear to care little for the quality of the output, then the whole place sucks and so does there work. All their work, you can feel it in the lobby on the helpline, or when you talk to a salesmen. The reverse is also true, when there is genuine ethical leadership the whole organization rocks and you can feel it everywhere.
With that in mind you can understand why the repugs create self-fufilling reality. How well do you think government employees perform.when.their political masters are constantly saying how much suck amd that "you are the problem". Not to mention when they themselves are caught witheir hand in the cookie jar.
So, it starts with the electorate. Choose ethical, dedicated, self-sacrificing leaders and you will have good government.
Hmmm...actually this whole "individual always above the group", and anything collectove being.villified,.means your.probably doomed to have bad leadership public and private.
Accept in that one instituion that makes a science of encoraging hive thinking and group above individual, the USA military.
