I'm from Poland, living in UK. In Poland, older people value privacy a lot, because they remember communism, secret police and censorship, while young people don't care as much. In UK, I've heard multiple times from older people that they don't care about privacy and that they trust the government 100%, while young people are more privacy conscious.
I'm a software developer in training from west Germany. We discussed this "nothing to hide" topic in our class (ages about 17 - 30) and about half of them didn't care or even appreciated surveillance.
