Imagine negotiating with an employer, except your inner monologue is always spoken aloud.
One unintended (?) consequence of extreme transparency for governments, is that it makes government ineffective and easily subverted or outmaneuvered by opaque organizations, like corporations and less liberal state actors.
By the way, this goes hand in hand with the encroachment on ordinary citizens' rights (often with exceptions being carved out specifically for parliamentarians).
Obviously you want your elected representatives to do what's best, not what gets you trending in the polls. In this particular case we should expect the EU to step up and help out member-states in need in spite of the political abuse and exploitation by populist parties of problems such as the sovereign debt crisis.
I agree, but an advantage over whom exactly? In this case it's simply an advantage of the ruling political and economic elite over European citizens (Greeks especially).
There are few instances when things really should be kept secret e.g. during wars, but this was not one of them.
What, Varoufakis is a world-renown professor of game theory. You don’t think he has an agenda? Is it impossible that this agenda clashes against the Good of Greek People?
Not quite, the problem are extremist and populist political parties who abuse any crisis to force their way into relevance without playing any constructive role in any part of the problem. There's a long list of examples in European history of how extremistm exploits economic and financial crisis for their own self-interest and in the process causing a long steam of suffering and misery. It happened often enough to enable us to learn from that mistake.
Not necessarily. If there is secrecy within the organization, any leader of a subbranch can abuse his power along the line of the movie Dr. Strangelove.
States create and enforce the laws, they can do whatever they want. Their only limit is the people willingness expressed via elections.
Corporations can never be above a State if they play in a game where the State decides the rules.
