This question has strong arguments on both sides — I'll pull current tax data and proposals to give you a balanced view.
Whether the wealthy should pay a higher tax rate than they do now is a debated question of values and economics, not just math. Here is how the current system works and the main arguments on each side:
Current System
The U.S. has a progressive federal income tax, where higher incomes face higher statutory rates.
•The current top statutory marginal rate is 37%. That rate applies only to income above the top bracket threshold, not all income.
•The figure reveals a generally progressive system: Overall, estimated effective tax rates steadily rise from -12.4% in the lowest-income decile to 25.0% in the highest — a difference of about 37 percentage points. Negative rates at the bottom result from refundable credits.
•For 2024, Treasury estimates show the top 1 percent will pay an average rate of 31.5 percent this year, compared with 10–12 percent in the middle and about 0 percent at the bottom.
•The average tax rate on the top 1 percent has hovered around 30 percent for four decades.
•Other estimates show different trends for the very wealthiest: Total effective tax rates for the 400 wealthiest Americans fell from 30% in 2010–2017 to 23.8% in 2018–2020, partly because they were able to shelter more business income and pay lower rates on reported income.
Historical context matters:
•The top marginal rate has varied widely, from over 70% in the late 1960s and 1970s and over 90% during World War II, to 50% in 1986 and 39.6% in 2017 before the current 37%.
•When the highest tax rate was between 70 percent and 90 percent, the wealthiest 1 percent of Americans paid less than 20 percent of the income tax burden. Today, with a tax rate of 37 percent, the rich pay almost 40 percent of the income tax burden.
•Similarly, in 1986, the top marginal income tax rate was 50 percent, and the top 1 percent paid 25.8 percent of all income taxes; thirty years later, the top marginal income tax rate had fallen to 39.6 percent, but the top 1 percent’s share of income taxes had risen to 37.3 percent.
Public opinion is mixed: A Reuters/Ipsos poll found nearly two-thirds of respondents agree that the very rich should pay more taxes, while Stanford survey research found only minority support for implementing a tax schedule radically more progressive than the one in place today.
Arguments FOR Raising Rates on the Wealthy
1.Ability to Pay and Fairness: Proponents argue wealth contributes directly to well-being over and above consumption it can finance, and therefore the wealthy have a greater ability to pay. They also point to strategies where wealthy households can finance consumption without paying capital gains by following a "buy, borrow, die" strategy.
2.Revenue and Inequality: Some research estimates if Congress were to increase the top marginal tax rate to 44%, it would yield annual revenue gains of about 3.1 percent with no discernible costs in terms of GDP, private investment, or wages. Higher taxes on the rich are also associated historically with lower levels of income and wealth inequality, though isolating cause and effect is difficult.
3.Restraining Excess Compensation: A 70 percent top tax rate can act as a restraint on the compensation of super-high-paid executives and others through its effect on the effort these individuals put into bargaining for pay above $10 million. The net return to such bargaining will be much more modest with a 70 percent top marginal tax rate than under the current top rate of 37 percent.
4.Addressing Loopholes: Supporters note the top federal marginal tax rate on long-term capital income is 23.8% while the top marginal ordinary income and payroll tax rates on wages is 40.8%, and argue raising capital gains rates would equalize treatment of work vs. wealth.
Arguments AGAINST Raising Rates on the Wealthy
1.Behavioral Responses and Revenue: Critics warn that people may change their behavior when tax rates increase:
•they can work less… as tax rates increase, the number of hours worked by a given individual would decrease and thus dampen the revenue effects
•People can shift income into nontaxable forms
•They can underreport income
When the highest tax rate was 70-90%, the rich sheltered income, which is why high rates failed to increase their share of taxes paid.
2.Already Progressive Burden: Opponents cite Treasury and CBO data that all official sources find that tax rates on high earners are much higher than tax rates on lower- and middle-income folks, with the top paying about twice the rate of the middle class.
3.Economic Efficiency: Some economists argue there is a trade-off between raising revenue and minimizing distortions, and lawmakers should construct a tax system that will raise revenue while minimizing distortions. Critics of steep hikes worry about reduced investment, entrepreneurship, and that there aren't enough wealthy people to tax to fund large spending programs without eventually taxing the middle class.
4.Alternative Reforms: Some Americans who support a flat tax do so not to maintain low rates on the rich, but because they see the flat tax as a means to eliminate loopholes for the wealthy, thus increasing their tax burden, on net.
Bottom Line
The decision often comes down to which goals you prioritize:
•If the priority is reducing inequality, funding public programs, and ensuring equal sacrifice, raising effective rates on high incomes, capital gains, or wealth is seen as justified.
•If the priority is economic growth, tax efficiency, avoiding avoidance, and recognizing the existing progressive burden, keeping rates at or near current levels — while closing loopholes — is seen as preferable.
Many policy proposals try to bridge this by not just raising the statutory 37% rate, but by broadening the base — e.g., taxing unrealized capital gains, capping deductions, or equalizing rates on capital and labor income — rather than simply increasing the top bracket.
