The typical Baby-Boomer is a guy born in 1951. The 18 years old hyppie who was drunk at Woodstock in 1969 and the 30 years old yuppie in 1981 who voted for Reagan is often the same person. Baby-Boomer were idealistic, individualistic, narcissicist and definetely self-absorbed.
The typical X is born in 1971. As a child he saw Baby-Boomers praise free love and free sexualty, but when he was in age to practice sex, AIDS was here. In France, the X matured during the end of the 30 Glorieuses, economical crisis, explosion of unemployement and delinquency, including juvenile delinquency. Baby-Boomer were idealistic, individualistic, narcissicist and definetely self-absorbed, X are more adaptive, disillusioned and cynic.
For the "rebellious" thing, it depends. Actually, the generation theory say the BOOM Generation were Prophet of a new cycle, in rupture with the Silent Generation and the G.I Generation. Baby-Boomer and X who had them as paretns are often "rebellious", while Y who have Babay-Boomer and X as parents are very family oriented and usually feel understood by their parents.
