We don't want the NSA tracking us, because we get nothing in return. It tries to sell us on "terrorism prevention," but most people don't experience that benefit in a visceral way. But this is not to say Americans won't give up privacy for anything.
On the contrary, Americans are very, very cheap dates. For just a modicum of convenience, entertainment and comfort, I'm happy to give you a list of everyone I call and everywhere I go. That's more than I'm sure the NSA has on me. And despite your privacy concerns, most of you are exactly the same way.
