# Black Tuesday (1929) On **October 29, 1929** — "Black Tuesday" — the New York Stock Exchange experienced its most devastating single-day crash, with 16.4 million shares traded in a panic sell-off that wiped out billions in value. Combined with the preceding "Black Thursday" (October 24) and "Black Monday" (October 28), the crash ended the speculative bubble of the 1920s and triggered the **[[Great Depression]]** — the worst economic catastrophe in American history, which by 1933 had produced 25% unemployment, 9,000 bank failures, and a 30% contraction in GDP. Black Tuesday matters for the KB as the **consequence of Gilded Age economics applied through government** — specifically, [[Andrew Mellon]]'s 1920s tax cuts (73% → 24% top rate), weak financial regulation, and speculative excess. The crash discredited laissez-faire economics for a generation, produced the [[New Deal]] regulatory state, and created the economic conditions that fueled both the rise of [[Father Charles Coughlin]]'s populist demagoguery and the [[America First Movement]]'s anti-interventionism. Without the Depression, there is no Coughlin, no [[Nye Committee]] narrative about bankers profiting from war, and no mass base for isolationism. ## What Happened **The bubble:** The 1920s boom, fueled by Mellon's tax cuts and loose credit, produced a speculative frenzy: - The Dow Jones Industrial Average quadrupled between 1924 and September 1929 - Margin buying (purchasing stocks with 10% down) meant average investors were leveraged 10:1 - Brokers' loans for stock speculation reached $8.5 billion by October 1929 - The Federal Reserve, constrained by political pressure, failed to tighten credit sufficiently **The crash:** - **October 24 (Black Thursday):** 12.9 million shares traded; prices plummeted; a consortium of bankers (echoing J.P. Morgan's 1907 intervention) briefly stabilized the market - **October 28 (Black Monday):** The Dow fell 13% — the bankers' consortium did not intervene again - **October 29 (Black Tuesday):** 16.4 million shares traded; the Dow fell another 12%; panic selling overwhelmed all buyers - By mid-November: the market had lost ~40% from its September peak - By July 1932: the Dow had fallen **89%** from its 1929 high **The Depression:** - GDP fell 30% (1929–1933) - Unemployment reached 25% (1933) - 9,000+ banks failed, wiping out depositors' savings - Farm income fell 60%; foreclosures swept rural America - Homelessness, hunger, and social desperation became mass phenomena ## Why It Matters for the KB ### Discredited Laissez-Faire (Temporarily) The crash and Depression destroyed the intellectual legitimacy of the Mellon/Coolidge economic philosophy for a generation. The argument that low taxes and minimal regulation produced prosperity — vindicated (apparently) by the 1920s boom — was demolished by the catastrophe that followed. This opened space for: - The **New Deal** (1933–1938): The regulatory state that movement conservatism spent the next 80 years trying to dismantle - The **[[National Labor Relations Act]]** (1935): Labor rights that Taft-Hartley would later constrain - **Glass-Steagall** (1933): Banking regulation that Reagan-era deregulation would erode and Clinton would repeal (1999) - **Social Security** (1935): The welfare state that "starve the beast" strategies target ### Created the America First Base The Depression's economic devastation created the conditions for the America First coalition: - **Father Coughlin's audience:** 30 million radio listeners tuned in to hear someone blame "international bankers" for their suffering — the populist anger that Coughlin channeled into antisemitism - **Nye Committee resonance:** The argument that WWI was a "bankers' war" resonated because the same banking class that profited from war loans had presided over the crash. [[Gerald Nye]]'s "merchants of death" narrative fell on fertile ground. - **Isolationist logic:** "Why should we fight for the international financial system that just destroyed us?" — the Depression made non-interventionism emotionally compelling in ways that abstract constitutional arguments never could - **[[Gerald L.K. Smith]]'s base:** The Share Our Wealth constituency (people who had lost everything) was available for radicalization ### The Mellon Pattern Repeats The crash demonstrated the pattern that conservative economics has repeated: | Cycle | Tax cuts / deregulation | Boom | Crash | Regulatory response | |-------|------------------------|------|-------|-------------------| | 1920s | Mellon Plan (73%→24%) | Roaring Twenties | 1929 crash → Depression | New Deal | | 1980s–90s | Reagan cuts + S&L deregulation | 1980s–90s boom | S&L crisis, then 2008 | Dodd-Frank (partial) | | 2000s–10s | Bush cuts + financial deregulation | Housing bubble | 2008 financial crisis | Dodd-Frank (weakened under Trump) | | 2017+ | TCJA + DOGE deregulation | (Ongoing) | (TBD) | (TBD) | ## See Also - [[Andrew Mellon]] — Treasury Secretary whose tax cuts fueled the bubble - [[Gilded Age Plutocracy]] — The economic philosophy that produced the crash - [[Father Charles Coughlin]] — The radio demagogue the Depression created - [[Gerald Nye]] — Nye Committee investigator whose "merchants of death" narrative was powered by Depression anger - [[America First Movement]] — The anti-interventionist coalition the Depression's conditions enabled - [[Panic of 1907]] — The previous financial crisis, resolved by Morgan's private intervention
