==== 2. Broad Historical Pattern (1790–2000 in Brief) ====
# 1790–1860 - Stress around the Executive and Proletariat grows significantly during the early Republic and pre–Civil War era. For instance, the Executive Stress from -3 (1790) up to -5 (1860) suggests intensifying tensions leading up to the Civil War. - Property Owners’ capacity and node value rise steadily, reflecting the dominance of landholding and the agrarian/early industrial economy. - Army often has moderate capacity/stress until the 1860 period, when it sees a spike (Army Stress moves from -1/-2 to -2 or -5 around wartime).
# Civil War and Reconstruction (1860s–1870s) - 1860 shows large negative stress for Executive (-5) and growing capacity in the Army (6 for Coherence, 6 for Capacity) just as the Civil War breaks out. - Postwar realignments lead to partial recovery in Executive and continued strong property ownership metrics.
# Industrialization and Gilded Age (1870s–1900) - Strong expansions in “Trades/Professions,” “Property Owners,” and “Shopkeepers/Merchants.” - Proletariat metrics gradually rise (e.g., Coherence from 3–5 up to 5–7 by 1900), consistent with an expanding urban workforce. - Occasional stress spikes around major panics (1873, 1893), though not always shown here year by year.
# Progressive Era to WWII (1900–1945) - Rapid increases in overall capacity and node values for many groups, culminating in WWII with extremely high stress in some areas but also very high capacity (Army in particular). - 1930s shows a big drop in capacity for the Executive (especially 1930–1933) with large negative stress, aligning with the Great Depression. Then, the system adapts via New Deal policies—seen in the partial recovery 1934–1936.
# Post-WWII Boom (1950–1970) - Many nodes (Executive, State Memory, Trades/Professions, Shopkeepers) have relatively high capacity and moderate stress. This is the well-known postwar economic boom. - Occasional dips in the 1960s (e.g., 1968 with major social unrest, the Army’s capacity/stress changes, and the Executive’s stress creeping upward) highlight the civil rights era and Vietnam War tensions.
# 1970–2000 - Multiple shocks: oil crises (1973, 1979), high inflation, Watergate (1974: Executive has -9 stress, capacity of 5). - The 1980s show partial recovery, especially in economic nodes (Property Owners, Trades/Professions) but persistent underlying tensions (Executive stress often around -4 to -6). - By 1990–2000, we see major improvements in certain measures for the Executive, Property Owners, and State Memory—consistent with the “end of the Cold War,” an era of relative global hegemony, and the 1990s tech boom. For example, in 2000, many nodes (Executive, Army, Property Owners, Trades) jump to high capacity (8–10) with near-zero or positive stress.
