I remember last time it took a day--- title: Decade-by-Decade Timeline
The Timeline of Decline (1900-2025)
Visual progression of American social coherence across 125 years.
The Decades
1900-1940: The Baseline
High coherence, tight-knit communities, shared moral vocabulary
1940-1950: Post-War Peak
Maximum institutional trust, family stability, economic prosperity
1950-1960: The Fissure
Cracks appear in conformity, seeds of counterculture planted
1960-1970: The Fracture ⚡
CRITICAL PERIOD — Phase transition begins (1962-1965)
1970-1980: The Malaise
Visible collapse, stagflation, divorce revolution, Watergate
1980-1990: The Mirage
Debt-fueled prosperity masks underlying social rot
1990-2000: End of History
Tech boom, civic organization death, “Bowling Alone” era
2000-2010: The Shock
9/11, housing bubble, institutional failure becomes undeniable
2010-2020: Polarization
Social media fractures reality, truth becomes tribal
2020-2025: Terminal Entropy
Pandemic, riots, total loss of shared meaning
