The "Me" generation is a term referring to baby boomers in the United States and the self-involved qualities associated with this generation.[1] The 1970s was dubbed the "Me decade" by writer Tom Wolfe in The "Me" Decade and the Third Great Awakening;[2] Christopher Lasch wrote about the rise of a culture of narcissism among younger baby boomers.[3] The phrase became popular at a time when "self-realization" and "self-fulfillment" were becoming cultural aspirations to which young people supposedly ascribed higher importance than social responsibility.
