What you fail to understand is that the government is not a single entity, it's not just a big 'the government,' it's a large organization of continuously changing people, and if there's is one thing that life should have taught you, it's that no matter how tight you think you are, there is always someone who can't keep a secret.
There are no conspiracies, the government is not out to get you, the government is not 'money hungry,' it's actually massively in debt. That is such an ignorant thing to say anyways, 'all they want is money!' Why? What the **** would they do with it? Government officials have a set pay, and the ones that are paid the most, Congress and the President, have to work to be consistently reelected. There is no motivation for any part of the government to simply 'make money.' Our government budget last year had a $400 billion deficit.
Outside of national placement and movement intelligence, there is no large secret they're keeping from you. Get over it.
