Should the wealthy pay a higher tax rate than they currently do?

Both sidesSays it is contested

Short answer: it depends on your goals and how you design the taxes. There isn’t a single “right” rate, but you can reason it out.

Reasons to support higher rates on the wealthy

•Ability-to-pay and fairness: an extra dollar means less to high earners (diminishing marginal utility), so a higher marginal rate can be equitable.
•Inequality and mobility: widening income/wealth gaps can reduce opportunity; more progressive taxes can fund education, health, and infrastructure that expand mobility.
•Fiscal needs and debt: if you value stronger public investment or deficit reduction, raising effective rates at the top is one of the least painful ways to raise significant revenue.
•Economic research: many studies find room to raise top effective rates if you also curb avoidance and broaden the base; capital-income preferences often make effective rates at the top lower than they look.

Reasons to oppose higher rates on the wealthy

•Growth and innovation concerns: if top earners respond strongly to higher rates by working, investing, or risk-taking less—or by shifting income abroad—the economic cost can outweigh benefits.
•Tax competition and mobility: capital and some people can move; very high rates may erode the base unless coordinated internationally.
•Complexity and avoidance: with a leaky base, simply increasing statutory rates can amplify loophole-chasing rather than raise much revenue.
•Preference for smaller government: if you doubt government efficiency or prefer private provision, you’ll be skeptical of higher rates.

If you do want more progressivity, design matters more than the headline rate

•Broaden the base first: limit high-end deductions, exemptions, and shelters; tax more kinds of income similarly to reduce gaming.
•Focus on capital income: narrow the gap between ordinary income and capital gains/dividends; address “step‑up in basis” at death; target clear economic rents (e.g., monopolistic or location rents).
•Use surtaxes or minimum taxes aimed at very high effective incomes rather than big hikes across a broad bracket.
•Strengthen enforcement and reporting to reduce evasion and avoidance; coordinate internationally to limit profit-shifting.
•Pair changes with pro-growth elements (expensing for genuine investment, R&D incentives, simpler rules) to dampen efficiency costs.

Bottom line

•If your priorities are reducing inequality, funding public goods, and stabilizing debt—and you pair higher top rates with base-broadening and strong enforcement—then yes, there’s a solid case for higher effective tax rates on the very wealthy.
•If your priorities are maximizing after-tax returns, minimizing government size, and avoiding potential efficiency losses—and you think avoidance/mobility responses would be large—then you’ll likely oppose raising them and favor base-broadening without higher rates.

If you share your country, the kinds of taxes you mean (income, capital gains, estate, wealth), and your goals (revenue, fairness, growth), I can sketch a concrete package and its likely trade-offs.
