How to convert between wealth and income tax
A blog post arguing that a 1% annual wealth tax is “mathematically equivalent” to a 20% income tax increase, assuming a 5% return on capital, has reignited debate over how to tax billionaires versus wage earners. Commenters contend the framing is misleading because most ordinary people have little taxable wealth while the ultra‑rich often pay very low effective rates through unrealized gains, borrowing, and inheritance strategies. Alternatives raised include higher or better-enforced capital gains and estate taxes, land or consumption taxes, and targeted fixes to loopholes, alongside broader concerns about inequality, democratic legitimacy, and the political risks of concentrated wealth.
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.
