The folks who don’t want to let a crisis go to waste have been very busy in the era of coronavirus, pushing an ever-expanding menu of bad ideas.
- Propping up high-tax states such as New York, Illinois, and California by restoring the tax code’s deduction for state and local tax payments.
- Hindering the efficient allocation of capital
and making it more difficult for companies to distribute profits to owners by banning or restricting “stock buybacks“ - Discouraging job creation and reducing take-home pay with a new federal mandate/entitlement for paid sick leave.
- There are also very bad ideas in Europe, such as the proposal that well-governed nations should be liable for the debts of poorly-governed nations.
Now we have another bad idea to add to the list.
A professor from Yale Law School, Daniel Markovits, argues in a column in the New York Times that the virus is a great excuse to impose a wealth tax.
Our extraordinary battle against the pandemic should draw on the immense reserves that the most privileged among us have accumulated over decades of abundance. To achieve this goal, America should institute a wealth tax.
…the relief effort should be funded through a one-time wealth tax imposed on the richest Americans… An exemption for the first $2.5 million of household wealth would exclude the bottom 95 percent from paying any tax at all and leave the top 5 percent with total taxable wealth of roughly $40 trillion. A 5 percent tax on the richest 5 percent of households could thus raise up to $2 trillion. …this one-time wealth tax…appeal ought to cross partisan lines. …A wealth tax would fund the relief effort in a way that gives meaning to shared sacrifice in the face of a universal threat.
My initial suggestion for Professor Markovits is the same one I put forth for Bill Gates. He should lead by example and donate a big chunk of his income, as well as the bulk of his savings and investments, to the IRS.
As an Ivy League professor, I’m sure he’s comfortably positioned as a member of the infamous “top 1 percent” of taxpayers, so he can be a guinea pig for his idea. To make things easy, the government has a website for him to use.
But let’s set aside snark and focus on the economic consequences. This issue deserves serious attention, not only because it is a threat in the United States, but also because it’s becoming an issue in other nations.
Such as Argentina.
Argentine Economy Minister Martin Guzman has backed the idea of a wealth tax on the country’s rich…to…find money to help
cope with the Covid-19 pandemic. The tax would affect 11,000 people with fortunes of at least $2 million, Guzman said… He spoke in an interview with journalist Horacio Verbitsky, published on the website El Cohete a la Luna. President Alberto Fernandez, in a separate interview, spoke of the need for wealth redistribution.
And South Africa.
The South African government will consider a proposal for a one-off wealth tax during an economic recovery planning meeting…
Such a tax could assist Africa’s most industrialized economy as it bounces back from the coronavirus outbreak and a five-week lockdown that is scheduled to be lifted on 30 April. The proposal comes from a group of economists, led by former South African National Treasury budget chief Michael Sachs.
The big problem with all of these proposals is that they ignore the crippling economic impact of wealth taxation.
The important thing to understand is that such taxes impose very punitive implicit tax rates on saving and investment. 
As seen in the accompanying chart, the actual tax rate depends on how well affected taxpayers are investing their money.
And it doesn’t take extreme assumptions to see that many taxpayers will face implicit tax rates of more than 100 percent!
And since all economic theories – even foolish ones such as socialism – agree that saving and investment are vitally important if we want higher living standards, any sort of wealth tax is a big mistake.
Actually, that’s an understatement.
In a normal economy, a wealth tax is a big mistake. But we’re now dealing with the very painful economic fallout from the coronavirus.
We will have a desperate need for lots of private capital if we want to restore prosperity as fast as possible, which is why imposing a wealth tax nowadays (in addition to other forms of double taxation that already exist) would be a catastrophic blunder.
And if the class-warfare crowd succeeds in their campaign to punish the rich, poor people will suffer the most.
P.S. Some people argue that a one-time wealth tax, similar to what Prof. Markovitz proposes and what South Africa is considering, wouldn’t have adverse economic effects because it penalizes productive behavior in the past (and there’s no way for people to reduce work, saving, and investment that already took place). But as I explained when debunking IMF arguments for a one-time wealth tax, this assertion is flawed because a) people will adjust their behavior when such a tax is discussed, b) people won’t trust it is a one-time tax, and c) the money will be used to finance a larger burden of government spending.
