Right, in a really, really ideal society, you wouldn't need to keep this kind of thing secret.

I understand salaries are already public in Norway. Why shouldn't they be? Unless you can't justify your earnings, for some reason.

I understand the 'big brother!' response to this kind of thing, I'm also squeamish about it. It does rely on a government that is trustworthy and accountable. But I don't think secrecy, paranoia, etc, is beneficial, compared to more openness.
