As a birth cohort, they never rose in protest as a unified political entity. Because "following the rules" had proven to be successful for Silents and had led to incredible and stable wealth creation, it was common that their Boomer and Gen X children would become estranged from them due to their diametrically opposite rebellious nature, vocal social concerns, and economic hardship unknown to the Silents, creating a different generational consciousness. For example, the Boomer children were instrumental in bringing about the counterculture of the 1960s, and the rise of left wing, liberal views considered anti-establishment, those of which went directly against the "work within the system" methodology that the Silents worshipped. Gen X children grew up in the 1970s and 1980s with the threat of nuclear war hanging over them and a resultant bleak view of the future, contributing to their generational disaffection, in contrast to the optimistic outlook of their Silent Generation parents.
