Debt and Deficits: Time to Worry?
Jun 26, 2026 · 1h 13m
Summary
Cardiff Garcia interviews Martha Gimbel, head of the Yale Budget Lab, about how rising U.S. debt and deficits are already harming living standards by driving up interest rates. Gimbel explains that government borrowing crowds out private investment, increasing costs for mortgages and business loans, while warning that sustained deficits could lead to slower long-term economic growth. She critiques the political avoidance of fiscal responsibility, noting that entitlement spending and tax cuts exacerbate the problem without generating proportional economic benefits.
