While, like many, I am appalled at the NSA's supposed massive-scale surveillance, I fear surveillance by corporations like Google much more. The fact that people share their most private information with Google voluntarily actually makes it worse. If you want to know where real power lies, look for power that is not only feared, but loved (say, your mother :)). Many people have referred to the book 1984 in the past week, but they've all missed one crucial point: Big Brother is not feared; he is loved. At the end of the book, Winston voluntarily subjugates himself to Big Brother. He loves Big Brother.
As long as the NSA has some form of oversight, however dysfunctional -- as long as government is at least suspect -- we'll be fine. But the much bigger danger is Google itself, the power that people love; that they voluntarily subjugate themselves to. It seems that Americans, perhaps because their government was formed not from feudalism, but as a rebellion against a foreign central government -- are very much aware of the dangers of government, but are blind to the much bigger threat of feudalism.
