When the rate of return on capital exceeds the rate of growth of output and income, capitalism automatically generates arbitrary and unsustainable inequalities that radically undermine the meritocratic values on which democratic societies are based. The past devours the future: wealth originating in the past automatically grows more rapidly, even without labor, than wealth stemming from work. Market forces and capitalism by themselves aren't sufficient to ensure the common good and to limit the concentration of wealth at levels that are compatible with democratic ideals.

Governments should tax capital, not labor, as AI makes human work less central to the economy

Verification History

AI Unverifiable Quote attributed to Thomas Piketty (French economist, 2013): "When the rate of return on capital exceeds the rate of growth of output and income, capitalism automatically generates arbitrary and unsustainable inequalities... The past devours the future... Market forces and capitalism by themselves aren't sufficient to ensure the common good and to limit the concentration of wealth..." These are genuine, well-known passages from Piketty's "Capital in the Twenty-First Century" (2013/2014) — the r>g thesis and the famous "the past devours the future" line. The source_url is en.wikiquote.org/wiki/Thomas_Piketty, a SECONDARY source, and it returned HTTP 403 to WebFetch so I could not directly confirm the page lists the quote; however, web search corroborated the r>g framework as Piketty's verbatim argument and the attribution is unambiguous. Vote 'for' on statement #436 ("Governments should tax capital, not labor...") aligns perfectly — Piketty is the foremost advocate of progressive capital/wealth taxation. TWO CAVEATS per guidance: (1) Year is 2013 (pre-2025/2026); I searched for a recent 2025/2026 Piketty quote on taxing capital/AI to replace it but found no cleanly-sourced verbatim recent statement (his most recent relevant work, "Rethinking Capital and Wealth Taxation" with Saez/Zucman, is 2023), so I did not delete/replace to avoid creating an unsourced quote. (2) The source is Wikiquote (secondary), not the primary book; ideally it should be updated to a primary citation, but I lack a stable accessible primary URL. Marking ai_unverifiable because the source page could not be fetched and is secondary/dated; attribution and vote alignment are sound. · Hector Perez Arenas claude-opus-4-8 · 9d ago
