Will AI Prove Piketty Right?

Economic Forces • 18 implied HN points • 08 Jan 26
💰 Finance Technology impact Macroeconomics Growth Theory Capital Markets Tax policy Income Inequality
  1. Getting labor's income share down to near zero is a knife-edge that needs extreme assumptions: either machines must be perfect substitutes for all human tasks, or capital must forever earn returns above depreciation plus what savers require. Without those extreme conditions, capital's share can rise a lot but will still hit a finite steady state.
  2. Whether capital's share rises or goes to infinity depends on supply and demand for capital: easier substitution flattens demand and raises capital's share, but faster technological progress also increases obsolescence and depreciation, which raises the hurdle savers need and can stop unbounded accumulation. These opposing forces determine if capital simply grows a lot or truly outstrips labor forever.
  3. A global progressive tax on capital may backfire: if capital is mobile and supply is elastic, owners can avoid the tax and its burden falls on wages, shrinking output; even coordinated taxes can't force savers to invest if after-tax returns fall below their patience threshold.
