Paul Krugman: Economics of Innovation, Automation, Safety Nets & UBI | Lex Fridman Podcast #67

Krugman’s ideal society resembles a “slightly imaginary Sweden”: strong safety nets, environmental regulation, and a distribution where no one is destitute and the very rich still inhabit the same basic material world as everyone else.

Drawing on Arrow, Krugman notes that effective competition requires informed, rational participants and good information—conditions that don’t hold in healthcare and often not in health insurance or education, making regulation and public provision necessary complements to markets.

Unlike other advanced economies, the US lacks universal healthcare and has weak support for children and long-term care; Krugman argues this cruelty not only violates justice but also undermines long-run economic potential by harming health, development, and productivity.

Krugman points out that overall productivity growth has been modest, not explosive; while some occupations shrink (like longshoremen or translators), this kind of sectoral churn is historically normal, and there’s no evidence yet of a qualitatively new automation era justifying panic or UBI.

He emphasizes that choices about unions, labor policy, and the welfare state explain much of the income distribution—e.g., Denmark faces the same technology and global markets but maintains high unionization and lower inequality—contradicting narratives that blame ‘the robots’ alone.
