That depends on geographical and historical context. In my country (ex-Soviet Union), the opposite is true. Older people, who have experienced what totalitarianism and mass surveillance is (thanks to KGB), are very pro-privacy. My grandmother still tears up every single letter to the small pieces before dumping it, even though that's a casual utility bill. On the other hand, youth, that are used to share all their life details on Facebook, Twitter and whatnot, are mostly of "I have nothing to hide" attitude. Only minority of young people (usually more technically literate) understand how important privacy is and how powerful information can be.

EDIT: grammar.
