How to convert between wealth and income tax

Original Article ↗ Hacker News Discussion ↗

Wealth vs. income tax “equivalence”

  • The article’s core claim: a 1% annual wealth tax ≈ a 20% income tax on capital income (assuming a 5% “risk‑free” return).
  • Many commenters say the math is technically right for people living off investment returns, but:
    • It ignores that most people’s income is from labor, not capital.
    • It assumes a specific return (5% real vs nominal is disputed).
    • It quietly treats today’s largely untaxed unrealized gains as if they were already taxed like wages.

Who is actually affected?

  • Several note almost all real‑world wealth tax proposals kick in at 8–9 figures of net worth (e.g., $10M–$50M+), with exemptions for retirement accounts and primary homes.
  • Critics of the article argue it misleadingly frames this as if everyone’s savings or median‑wealth households would be taxed.
  • Others worry that thresholds will inevitably drift down over time (“slippery slope”), citing income tax history.

Fairness, power, and inequality

  • Pro‑wealth‑tax side:
    • Money is power; extreme wealth concentration is seen as incompatible with democracy.
    • Ultra‑rich can live off asset appreciation and loans while reporting little taxable income (“buy, borrow, die”), paying lower effective rates than workers.
    • A 1% wealth tax that functions like a ~20% income tax on capital is framed as catching up to what workers already pay.
  • Anti‑wealth‑tax side:
    • Argue capital is what makes labor more productive; taxing it heavily ultimately hurts workers.
    • Fear capital flight, more private equity, and asset‑hiding schemes, leaving the middle class to shoulder the tax.
    • See better targets in closing specific loopholes (step‑up in basis, asset‑backed loans) or beefing up estate taxes instead.

Implementation and design issues

  • Major practical concerns:
    • Valuing illiquid assets (private companies, art, closely held businesses).
    • Liquidity for “asset‑rich, cash‑poor” people, e.g., retirees or land‑rich families.
    • Interaction with existing capital‑gains and property taxes; some suggest integrating wealth tax as an “unrealized gains prepayment.”
  • Alternatives raised:
    • Stronger inheritance/estate taxes.
    • Consumption or VAT‑style taxes with rebates/UBI to reduce regressivity.
    • Land‑value taxes and higher property taxes as more enforceable, non‑mobile wealth taxes.

Meta and political framing

  • Many see politicians’ “mere 1%” rhetoric as deliberate downplaying; others say the article is the one obscuring that current top‑end effective rates are very low.
  • Thread is sharply polarized: some view wealth taxes as necessary to prevent oligarchy; others as self‑destructive populism that empowers already‑ineffective governments.
