Are websites like Facebook and Myspace an approval from my generation that privacy is not important?

One of my “conspiracy theories” are that we are headed for a complete surveillance state similar to the UK. NYC is installing surveillance cameras all over the city. In combination with The Real ID Act, section 202(b)(9), a common machine-readable technology, with defined minimum data elements, (notice how drivers licenses are now scannable and digital), whoever is in charge of surveillance cameras, can track whoever is in the area.

Are sites like myspace and facebook, where users often do not think twice about putting all information about themselves on these sites(myspace is also owned by Rupert Murdoch), means of easing people into being lenient of authority invading our privacy as long as it will “keep us safe?”
