Episode notes
Austerity Fails When Everyone Cuts Together
- Austerity is ineffective when applied simultaneously across nations because all cutting reduces aggregate demand and shrinks the economy.
- Blyth argues historical examples show simultaneous austerity deepened downturns, sometimes enabling extreme politics in the 1930s.
Private Bank Losses Became Public Debt
- The 2007–08 debt surge came mainly from converting private bank liabilities into public debt when governments bailed out banks.
- Blyth cites T-bill shortages, repo market runs, and bailouts that pushed OECD tax revenues down ~30%, raising debt-to-GDP from ~61% to ~100%.
How Welfare Enabled Blyth's Social Mobility
- Blyth recounts his upbringing as an orphan raised by his grandmother to show the welfare state enabled his social mobility.
- He uses this personal story to reject the claim that welfare caused his rise and to motivate his critique of austerity.
