A governments transparency is dependent on it's voters. Most voters are more interested in who rubs which private parts with whom, still I think the alternative without any government would be worse than it is today.
Please tell me that you are not making the false choice between what exists today and zero government, justify your suggestion that government is more productive/better/more transparent/less corrupt etc than private companies? That would be a heck of a false dichotomy.
I have nothing against government. I use their services (though perhaps less then most), but neither would I make the claim that they are automatically less corrupt than a private enterprise, and my personal experience bears this out.
I do not say that a government is automatically less corrupt, I am saying that they are likely to be less corrupt. Reason is that they need to be reelected by a majority of it's citizens instead of it's majority of shareholders. You cannot 51% a government in the same way as a private company where 1 person may own that 51%
Maybe you are right with respect to the subset of governments which are also have democratic institutions, maybe not, however consider this:
If we applied this test to Bitcoin, it would likely die.
The "voters" of the authoritative block chain are those that have invested their time and their energy and their wealth. They are more like shareholders than 1 person 1 vote democracy.
If we put the vote to the general population, Bitcoin, with all the scurrilous press it gets, would be easily 51%-ed.
Those with a vested interest in the success of an operation may also be the ones paying more attention to the details that matter.
Companies may have strict anti-corruption clauses in their contracts which allow for immediate termination on evidence of corruption, democracies have to wait for elections. People are people, being a government worker (which in many societies are more highly paid than private employees and get better benefits, and have more social power) does not make that person less subject to the things which may corrupt them, and quite possibly the opposite. It seems naive to think otherwise.
