The idea of the blank generation goes back at least to the 50s, and probably no further, that generation being the first to experience existential angst as a whole. Also the title of a good punk song by Richard Hell from the late 70s. Its funny that people are constantly hyping this 'no values' 'slacker'ism as the New Thing when every generation for a while has been going through this before they settled down and realized its all about MONEY.
