The more I think of it I thinkt that secrets are a tool of the rich and powerfull to keep the weak and poor subjugated. I for one think that a society with lots of transparency (think at least on financial transactions and wealth) would reach a more honest state.

And there are examples where this actually works - like the stock exchange: people agree that to be able to take good decisions, the publicly listed companies must be transparent.

Of course changing from "full secrecy mode" to "let's be more transparent" can't happen suddenly, but there are places where there are more transparent (ex: in Norway you can ask for someones tax declaration) and the country continues to function. And you can't do it in all places: if you are in a place where people hate each other for various reasons with passion (ex: skin color, place of birth, what you believe in etc.) then keeping secrecy is smart while the society solves the other things. If you think secrecy is what protect I think it is taking a huge chance. Hatefull people around will make at some point a mess and can affect someone, secrecy or not.
