Overview of Ten Myths About the U.S. Tax System (Update)

This Freakonomics Radio episode (updated) features Stephen Dubner interviewing Jessica Riedel, a longtime budget and tax expert (formerly Manhattan Institute, now Brookings). Riedel reviews what she calls the top 10 tax myths in U.S. debate, updates key fiscal numbers, and explains why the debt crisis is driven largely by spending (especially entitlements), not just by tax cuts. She also lays out pragmatic policy priorities: entitlement reform, realistic revenue choices (including more tax on the middle class), tax-code simplification, and process reforms to change political incentives.

Guest background and perspective

  • Jessica Riedel: career budget and tax expert (Heritage Foundation, Senate chief economist for Rob Portman, adviser on presidential campaigns). Now at Brookings (previously Manhattan Institute).
  • Self-described pragmatic, right-of-center, nonpartisan critic of fiscal irresponsibility.
  • Emphasizes empirical, numbers-first approach and often challenges both parties’ narratives.
  • Personal note: transitioned publicly from Brian to Jessica; cites supportive professional response.

Key fiscal context and numbers (as reported in episode)

  • U.S. national debt: about $39 trillion; ~124% of GDP (highest since post-WWII).
  • Recent annual deficit (as of episode): roughly $1.8 trillion.
  • Interest costs on debt have tripled since 2021 to nearly $1 trillion annually; projected to rise to ~$2 trillion in a decade.
  • Federal revenues ≈ 17% of GDP (historic average since 1960); projected spending to approach ~33% of GDP over 30 years.
  • Since 2000: taxes cut by ~2% of GDP; spending increased by ~6% of GDP — spending is the larger driver of deficits.
  • Social Security + Medicare projected cash shortfall (next 30 years): Riedel cites ~$124 trillion (unfunded obligations / cash deficits).

The 10 tax myths — quick corrections

  1. Myth: Tax cuts pay for themselves.
    • Reality: They can boost revenue a bit but almost never fully pay for themselves.
  2. Myth: Tax cuts “starve the beast” and force spending cuts.
    • Reality: Historically, tax cuts are followed by more spending; raising taxes has correlated with spending restraint.
  3. Myth: The middle class pays higher tax rates than the rich.
    • Reality: Combined federal taxes are heavily skewed upward: top 1% ≈ 33% effective share; middle ≈ 12%; bottom ≈ near zero or negative after credits.
  4. Myth: 1950s top tax rates (e.g., 91%) generated most revenue.
    • Reality: Very few taxpayers actually paid the statutory top rates; high top brackets raised little revenue.
  5. Myth: Europe funds big government by taxing the rich more than the U.S.
    • Reality: Europe’s higher revenues come mainly from VAT (consumption taxes) and high payroll taxes that hit middle and lower earners.
  6. Myth: Tax cuts for the rich are the primary reason for large budget deficits.
    • Reality: Since 2000, tax cuts explain only a small fraction (Riedel cites ~0.6% of GDP attributable to rich tax cuts); spending increases are the dominant cause.
  7. Myth: Taxing corporations and millionaires heavily can eliminate the deficit.
    • Reality: Even extreme taxation of the wealthy would not come close to closing the gap sustainably.
  8. Myth: Most 2017 tax cuts went only to corporations and the very wealthy.
    • Reality: In percentage terms, tax-rate cuts were roughly proportional across groups; richer people received larger dollar reductions but not vastly disproportionate rate changes.
  9. Myth: Rolling back Reagan/Bush/Trump tax changes would produce painless deficit reduction.
    • Reality: Reverting entirely would impose large tax burdens on the middle class, not just the rich.
  10. Myth: U.S. corporate taxes are far below international norms.
    • Reality: Pre-2017 the U.S. had the highest statutory corporate rate; post-2017 it fell but the U.S. remains in the upper third among developed countries on combined measures. When pass-through and other business taxes are included, U.S. business tax take is comparable or slightly higher.

Political dynamics and misinformation

  • Narratives sell: politicians on both sides promote “free lunch” claims to their bases (conservatives promise tax cuts with spending restraint; progressives promise taxing the rich to pay for expansion).
  • Data misuse: Riedel criticizes some administration measures (e.g., overstating wealthy people’s effective tax rates by counting unrealized wealth and omitting corporate/estate taxes).
  • Incentive problem: lawmakers privately acknowledge fiscal risks but fear electoral consequences of tough choices; many potential bipartisan reforms are developed behind closed doors because politicians won’t publicly back them.

Policy priorities and proposals Riedel discusses

  • Main point: spending (entitlements) is the core problem — tax fixes alone cannot close projected long-run gaps.
  • Entitlement reforms (Social Security / Medicare) must be central:
    • Options: raise payroll tax rates, raise retirement ages, means-test or reduce benefits for high earners.
    • Riedel’s stance: start with means-testing higher earners (e.g., reduce benefits for very wealthy retirees).
  • Tax code improvements:
    • Simplify code; eliminate many deductions and preferences.
    • Consider shifting toward consumption taxes (VAT or other consumption-based systems) — better for growth but politically difficult and must be designed to protect seniors and lower-income households.
  • Budget process reforms:
    • Adopt procedural constraints to force policymakers to “pay for” promises now (pay-as-you-go, scoring discipline) to change incentives.
  • Political feasibility: reforms likely require bipartisan, simultaneous packages (taxs + entitlement adjustments + spending discipline) to avoid being framed as partisan attacks.

Notable quotes & framing

  • “The laws of economics always win.” — Riedel’s reminder that political spin cannot change fiscal arithmetic.
  • “If you're going to reform benefits should you start with the poor or the rich? Start with the people who can afford it.” — Riedel on means-testing Social Security.
  • “Politicians promise big tax cuts and big spending; they dump the cost on people who aren’t going to pay it for 20–30 years.” — on intergenerational misalignment.

Takeaways for listeners

  • The U.S. fiscal gap is driven more by rising spending (especially entitlement growth and interest) than by tax cuts alone.
  • Common political narratives on taxes are often oversimplified or inaccurate; facts about who pays what are more nuanced (U.S. tax system is relatively progressive; middle-class effective tax rates are low compared to history and many developed countries).
  • Meaningful fiscal repair requires confronting entitlements, rethinking revenue sources (including realistic discussion of taxing the middle class or adopting consumption taxes), and changing political incentives through process reforms and bipartisan deals.
  • Small or symbolic cuts (theater cuts) will not address structural problems.
