Nobody in the world can not know everything, because, frankly, we do not simply allowed. The government always keeps some secrets and mysteries with the help of the laws of secrecy and privacy, which may be different in different countries, but the essence remains the same.
Of course, our right as citizens of a State, to know as much as possible, but many secrets remain secrets and most of us will never reveal them. Learn the secrets that are kept so carefully, as it could
The secret of the firm:
Kept secrets of the company - a necessary legal position. After all, a healthy competition is very important for a capitalist society, so many companies are doing everything possible to keep under lock and key that allows them well to keep afloat and not allow the market flooded with cheap imitations. In this case, guaranteed by the emergence of monopolies. For example, if anyone ever found out the secret formula for Coca Cola, the company will not be able to produce "single cola in the world", and each of us will be able to prepare a drink in his bathtub and spend much less. So today the Coca Cola Company has to do everything to at least another hundred years to hold the market at number 1, keeping their secrets.
Location of oil fields:
If the government does not keep a secret place where the oil reserves, and they became known to all, valuable land immediately began to disperse hand and deposits of valuable minerals would be insanely expensive.
There is a process by which the Government obtains information about what is happening in different countries, as well as individuals. These data add up to a special folder. The government can open this information to the public, but it happens very rarely and then after a certain period. May occur deliberate leak of information, or it may be a declassified. However, most government keeps the information secret for many years, to save his reputation.
