Tax policy is shaped disproportionately by concentrated wealth
Statement
Concentrated wealth funds the lobbying, think-tank, and campaign-finance infrastructure that shapes tax-policy design. The result is a tax system whose effective rates and structural carve-outs (capital-gains preference, step-up basis, pass-through deductions, foundation rules) favor wealth-holders disproportionately and progressively across decades — a self-reinforcing channel that distinguishes concentrated wealth from a static distributional outcome.

Causal links
Tax-policy capture by concentrated wealth lowers effective rates on capital and inheritance, accelerating top-share growth beyond the r > g baseline.
Concentrated wealth captures regulatory and political capacity, weakening horizontal accountability institutions and enabling executive aggrandizement.

Cross-domain synthesis: inequality → economic insecurity → authoritarianism
Synthesizes Rodrik (2018), Norris & Inglehart (2019), and Hsieh & Moretti (2019) into a causal chain from housing-supply-driven wealth divergence to right-populist vote-share growth across OECD democracies in the 2008-2024 window.
FindingThe inequality → economic-insecurity → authoritarian-appeal chain is empirically supported in the 2008-2024 window across the studied OECD countries, but with substantial cross-country heterogeneity. The strongest evidence is in cases where housing-mediated wealth divergence and trade-shock exposure compound (Rust-Belt US, post-2008 southern Europe). The chain does NOT predict authoritarian growth in low-inequality high-mobility cases (Scandinavia, where authoritarian shifts when they occur track different drivers).Data sources (3)- Rodrik — Why Populism? · 2018 — Cross-country regression linking economic-shock exposure (trade, labor) to right-populist vote-share growth, with consistent direction across 14 OECD countries.
