Foucault's style is (possibly deliberately) obtuse, and his knowledge of history dubious at best, per Keith Windschuttle's book The Killing of History: http://www.amazon.com/The-Killing-History-Theorists-Murderin... .

It's the question of why we all let this happen without any resistance

Because it's easy, because most of the time it doesn't affect us, and because it's hard for one voter to fix the problem. Bryan Caplan's The Myth of the Rational Voter is very good on this subject. Most people (and voters) don't even know how many Senators their state has, or their terms, let alone why complex subjects like privacy are important. Based on Caplan's book, I think ignorance is a more reasonable explanation than a fear of being anti-authoritarian or an institutionalized mindset.
