Unfair tax rates

Warren's argumentation is the following.

"The ultra-rich and powerful have rigged the rules in their favor so much that the top 0.1% pay a lower effective tax rate than the bottom 99%, and billionaire wealth is 40% higher than before the COVID crisis began. A wealth tax is popular among voters on both sides for good reason: because they understand the system is rigged to benefit the wealthy and large corporations. As Congress develops additional plans to help our economy, the wealth tax should be at the top of the list to help pay for these plans because of the huge amounts of revenue it would generate."^[1]

Upon including the cost of private health insurance, the wealthiest Americans currently pay an effective income tax rate of about 23% as opposed to almost 40% for middle class Americans. Warren's proposals would turn it into the richest paying significantly higher rates.^[3] If calculating the effective tax rate as a percentage of net worth, the difference or current tax rates gets even bigger. The bottom 99% of Americans pay about 7.2% of their net worth every year in taxes, per Warren. The top 0.1%, by contrast, pay about 3.2%.^[4] Being wealthy means having more opportunities to avoid or lower taxes since investment income is taxed at a lower rate than wage income. Because the payment is bound to citizenship and property, the bill can be a good way to tax foreign or unsold wealth. It could limit tax avoidance options.

Wealth gap

The tax aims to reduce the wealth gap. “The Ultra-Millionaire Tax Act would level the playing field and narrow the racial wealth gap by asking the wealthiest 100,000 households in America, or the top 0.05%, to pay their fair share,” Warren stated. "The hyper concentration of wealth among a tiny number of multimillionaires and billionaires is a crisis for American capitalism and the American Dream. Wealth inequality is at its highest level since the Gilded Age. The wealth share of the richest 0.1% has nearly tripled since the late 1970s," said Congressman Boyle.

Many people believe that widening the wealth gap is a natural characteristic of capitalism. In 2014, French economist Thomas Piketty warned in his book “Capital in the Twenty-First Century” that if the already rich were able to accumulate wealth faster than economies were able to grow, inequality would skyrocket in the coming decades, potentially destabilizing societies in the process. He proposes a system of progressive wealth taxes to avoid the negative consequences.^[5] However, his theory has been challenged by other economists.^[6]

The Ultra-Millionaire Tax Act is co-sponsored by Senators Bernie Sanders (I-Vt.), Sheldon Whitehouse (D-R.I.), Jeff Merkley (D-Ore.), Kirsten Gillibrand (D-N.Y.), Brian Schatz (D-Hawaii), Edward J. Markey (D-Mass.), Mazie Hirono (D-Hawaii.). It is also endorsed by many organisations such as Action Center on Race and the Economy, AFL-CIO, American Federation of State, County and Municipal Employees (AFSCME), Americans for Financial Reform, Americans for Tax Fairness and other.^[1]

Implementation

Although the proposal has gained support, it might be difficult to implement. First, valuating assets of wealthy is often complicated, especially for illiquid assets. It can be seen from the proposition itself that enforcing the tax will be expensive, with a significant part of the revenue having to be used for administration and auditing, as well as the fact that millionaires might still find loopholes to lower or avoid their payment. U.S. Treasury Secretary Janet Yellen stated in an interview that a wealth tax is off the table, as it's "something that has very difficult implementation problems." She added that "a wealth tax has been discussed," but it's not favored by President Joe Biden.^[7]

The Constitution

A wealth tax could be unconstitutional in the United States. Article I of the Constitution, Section 9, bars any "capitation, or other direct, tax". In 1895, the Supreme Court ruled that a federal income tax was therefore unconstitutional. The 16th Amendment made income tax constitutional, but it did not cover a wealth tax.^[4]

Economic arguments

The tax can force millionaires to sell their assets or limit investment, which can be harmful for the economy. It can discourage foreign investors to invest to United States since their property located in the U. S. will also get taxed. A 2020 Tax Foundation analysis of wealth tax proposals of Warren and Sanders found they would reduce U.S. economic output by 0.37% and 0.43%, respectively, over the long term.^[8] That means that even though the wealth gap might be reduced by wealth taxes, the standard of living might be lowered for everyone, especially if the tax gets higher or if it is imposed on more people in the future.

Some could also argue that the millionaires will leave the U. S. However, since "exit tax" is proposed, this is not very probable. Also, interstate migration is almost as twice as common among the middle class than among the rich.^[9] So millionaires will likely want to stay. The bill is also immune to capital transition, so capital flight is also improbable.

Other arguments

A wealth tax may not be the only way to solve the issues above. For example, different effective tax rates for the rich can be changed by adjusting current tax rates. Or biflation created by expansionary monetary policy might be a reason for wealth-gap increase during the COVID-19 crisis and avoiding it could be just as effective.^[10]

Historic experience with wealth taxes

In many European countries, wealth taxes were a failure. In 2018, president Emmanuel Macron cancelled France's wealth tax, which had caused capital flight, brain drain, loss of jobs, a net loss in tax revenue.

The rate was charged on individuals with a net worth over €1.3m (£1.14m), with the rate ranging from 0.5% to 1.5% on assets over €10m. However, the revenue was not as high as expected. In 2015, a total of 343,000 households paid €5.22bn, an average of about €15,200 per household. It accounted for less than 2% of France's tax receipts.

It also led to an exodus of France's richest. More than 12,000 millionaires left France in 2016, according to research group New World Wealth. In total, they say the country experienced a net outflow of more than 60,000 millionaires between 2000 and 2016. When these people left, France lost not only the revenue generated from the wealth tax, but all the others too, including income tax and Value-added tax.^[11]

Twelve European countries had a wealth tax in 1990. Today, there are only three - Norway, Spain and Switzerland. It was expensive to administer, hard on people with lots of assets but little cash, discouraged investments and it did not raise much revenue.^[12]

However, Warren argued her proposal differs from the ones already implemented and attempts to address some of the issues, especially with its 40% "exit tax".
