Underwood-Simmons Tariff Act (Revenue Act of 1913)

Class card for the US federal tariff-policy machine as reshaped by the Underwood-Simmons Tariff Act (Revenue Act of 1913), signed 3 October 1913 by President Woodrow Wilson. Represents the Progressive Era tariff-reform paradigm — the first significant downward revision of US import duties since the Civil War era (Morrill Tariff 1861 launched the upward-protectionist regime; McKinley 1890 and Payne-Aldrich 1909 were peaks at ~40% average dutiable rate). The Underwood Act reduced average dutiable-import rates from ~40% (Payne-Aldrich 1909) to ~26%; expanded the free list to include raw materials, food, agricultural implements, and consumer necessities; and targeted the protective schedules that had sheltered the Standard-Oil-era trust system. The act was designed in tandem with the 16th Amendment (ratified 25 February 1913, authorizing the federal income tax), constituting a deliberate fiscal substitution: income-tax revenue replaces tariff revenue as the primary funding source for the US federal state. This fiscal-architecture shift — from tariff-revenue-funded state to income-tax-funded state using tariffs as policy instruments (trade leverage, not revenue maximization) — is permanent and marks the structural break from the mercantilist-protectionist fiscal paradigm established in 1861. Sequencing of the 1913 Wilsonian settlement: 16th Amendment ratified Feb 1913 → Underwood Act signed Oct 1913 → Federal Reserve Act signed Dec 1913. Three co-designed pillars of the Wilsonian Progressive fiscal-monetary order. Contemporaneous with Clayton Antitrust Act 1914 and Federal Trade Commission Act 1914 — the full Wilsonian administrative-state agenda. Cordell Hull (congressman, then Secretary of State 1933–1944) traced the Underwood free-trade ideology directly through to the post-WWII multilateral trade order (Reciprocal Trade Agreements Act 1934, ITO predecessor, GATT 1947) — the ideological lineage from Underwood to Bretton Woods free-trade architecture is direct and documented. Policy-regime lifespan: 1913–1922 (9 years before Fordney-McCumber reversal under Harding). However the FISCAL PATTERN — income-tax-funded federal state; tariffs as policy tool not primary revenue — is permanent (1913 → present, ~110+ years). machine_lifespan modeled on the FISCAL PATTERN not the policy-instance reversal. Reversed as tariff-rate policy by Fordney-McCumber 1922 (Harding) and further by Smoot-Hawley 1930 (Hoover; catastrophic; precipitated Depression trade collapse). The free-trade Wilsonian paradigm revives post-WWII through Hull's Reciprocal Trade Agreements Act (1934), GATT (1947), and the Bretton Woods free-trade settlement — making Underwood the MM-Day progenitor of the post-war multilateral trade order. Cross-era forward: Underwood's free-trade/regulatory-tariff grammar is ancestral to EU GDPR Brussels-Effect regulatory-trade logic (DM) and BRICS counter-hegemonic trade-policy forms (DM).
