"Let's begin with an extreme example.
America has about 800 billionaires. Imagine we seized every single
dollar of their wealth—every home, property, business, investment, car,
and yacht, right down to their kids' teddy bears—and sold it all for
full market value.
That would raise enough revenue to finance the federal government for 9 months. Not 9 months out of every year: 9 months one time.
Then, with no billionaires left to pillage, it's gone—as is your
401(k), because most of that wealth would've been liquidated out of the
stock market.
Even taxing million-dollar earners at 100 percent marginal tax rates
wouldn't balance the long-term budget. Not even if each of those
taxpayers would keep working for zero net pay (and they would not).
Only slightly more realistically, imagine that President Bernie Sanders gets to implement his dream tax proposal: federal
income tax rates as high as 52 percent, an uncapped 15.3 percent
payroll tax on all wages, and capital gains tax rates of 62 percent—plus
the state tax rates on top of those. Sanders also proposed hitting
corporations with a world-leading 35 percent corporate tax rate that
includes all multinational income, a wealth tax rate as high as 8
percent, an estate tax rate as high as 77 percent, new financial
transaction taxes, and several other surtaxes.
Sanders' tax proposal would set marginal
income, capital gains, business, wealth, and estate tax rates at their
highest levels in the developed world. Total new revenues: approximately
1.5 percent of GDP, after accounting for losses to dampened economic
growth. That is a lot of money. But it's not enough to close more than a
fraction of a current-policy budget deficit heading toward 8 percent of
GDP in the next decade. And even those revenue figures implausibly
assume that people and corporations would continue working, saving, and
investing despite combined federal and state marginal tax rates on labor
and investment that would approach 80 to 100 percent.
Two years ago, I ran a model that set every upper-income and corporate tax policy at its revenue-maximizing level without regard to economic damage. It showed roughly 1.5 percent of GDP
in new revenues and much slower economic growth. This is not a good
tradeoff for an economy. The mathematical reality is that there just
aren't enough millionaires, billionaires, and undertaxed corporations to
close a 30-year budget deficit of between $115 trillion and $180
trillion, depending on the baseline we use. It is not possible to
finance annual deficits heading to $4 trillion in a decade and 14 percent of GDP
over the next 30 years on the backs of corporations and only 5 percent
of American families. There just are not enough super-rich people to pay
for the other 300 million of us. And most of the available tax base
resides in that large middle class.
Few Americans understand that our tax code is already extraordinarily progressive—more so than any other nation in the Organisation for Economic Co-operation and Development (OECD). And it's grown radically more progressive over the past 40 years. The top-earning 20 percent now pays 69 percent of all federal taxes, and the top 1 percent currently pays 25 percent of all federal taxes.
By contrast, the bottom-earning 60
percent of Americans—that's 3 out of 5 taxpayers—pay just 13 percent of
total federal taxes, including a combined negative income tax.
Last year the federal government
funded 263 days of spending by taxes instead of borrowing. Of that, the
top-earning 20 percent funded the government for 201 days,
or nearly 7 months. The next 20 percent funded 41 days. And the
bottom-earning 60 percent of Americans—which means most of the U.S.
population including the median-earners—funded the federal government
for just 21 days of the year.
That level of tax progressivity might
not be a bad thing. But most of the nation's total income comes from
families earning under $400,000. And their dramatically lower current
tax rates mean that the large majority of the available remaining tax
base resides within the tens of millions of these families.
No one likes the idea of raising middle-class taxes, but there's only
so much revenue to raise from the wealthy, even at exorbitant tax rates.
Advocates of dramatic tax-the-rich
policies often claim enormous potential revenues by invoking: 1) the
1950s income-tax brackets exceeding 90 percent; 2) European tax systems;
and 3) corporations that paid little to no taxes last year. The reality
is different.
Those 91 percent income tax rates from the 1950s averaged only 7.2 percent of GDP
in federal income tax revenues. As the top tax bracket fell to 70
percent in the 1960s and 1970s, income tax revenues actually rose to
around 7.8 percent of GDP. And in the time since all the dramatic
reductions of the top income tax rates starting in 1981, federal income
tax revenues have averaged 8.1 percent of GDP.
So Washington collects more income tax revenues as a share of GDP today
with a top tax bracket of 37 percent than it collected in the 1950s
with a 91 percent tax bracket. In fact, since 1950 the correlation
between the highest income tax bracket and revenues as a share of the
economy is -0.25 percent, meaning that higher top tax rates are
correlated with lower income tax revenues.
How can eras with higher top tax
brackets bring in less overall tax revenue? Because the highest income
tax brackets don't tell us much about the total income tax revenues.
What matters more are the income thresholds for every tax bracket, the
amount of tax preferences and tax deductions, whether the tax system
encourages tax avoidance and tax evasion, and—most importantly—broader
economic growth rates. Those dials can produce more tax revenues than
merely raising upper-income tax rates on a small number of taxpayers.
In fact, almost no one actually paid
those old 91 percent tax rates, which kicked in at today's equivalent of
a $4.1 million annual income. In 1961, that was only 446 families, and
it raised just 0.1 percent of all income tax revenues. Moreover, all of the tax brackets between 52 percent and 91 percent collectively produced just 1 percent more
income tax revenue than if we had capped those tax brackets at 50
percent. Those tax brackets won't even pay for 2 days a year of federal
spending. People are free to advocate 91 percent tax rates, but they
should not point to 1950s America as proof that they raise significant tax revenues that way.
What about the claim that Europe has shown how to finance large welfare states on the backs of the rich? In reality, those nations tax the wealthy at similar rates to the U.S. It is their heavy middle-class taxes that produce the typical OECD nations' 7.5 percent of GDP
tax revenue advantage over the US across all levels of government.
Specifically, every other OECD nation assesses a value-added tax
(VAT)—essentially a sales tax—as high as 27 percent. Without the
resulting 7.2 percent of GDP
in average VAT revenues, U.S. and OECD tax revenues are nearly equal.
Even the social democratic Scandinavian countries that collect 14
percent of GDP more than the US do it almost entirely from their VAT and
higher payroll taxes—which come from everyone, not just the rich.
America's top tax brackets for income, capital gains, corporate, and estate taxes are actually all slightly higher
than those of the typical OECD nations when merging all levels of
government. We've got the most progressive tax system in the OECD
because we tax the rich at similar rates as those other countries but we
tax middle- and lower-earners dramatically less than they do. So if you
want America to tax like Europe, then our middle class is going to get
the nastiest surprise of its life. Europe is no longer the caricature
Americans imagined decades ago.
Either way, eliminating those tax
breaks and taxing these companies more could raise perhaps $100 billion a
year. That's real money, but it's not a game-changer in the context of
those $4 trillion annual deficits we're heading toward. And, of course,
we'd lose the business investment and job creation that comes from those
bipartisan incentives.
Today, many wealthy individuals
escape short-term income taxes by receiving most income in capital gains
or borrowing against their wealth. The capital gains will eventually be
taxed when the investments are sold, unless they carry it through to
death. Ensuring that capital gains would be taxed at death or that rich
people can no longer easily borrow tax-free against their wealth would
be logical reforms—but they wouldn't raise revenue of any significance
to our deficits. We will still have to make difficult choices on
spending or middle-class taxes."
"Europe long ago learned the hard way
that going overboard on wealth taxes and steep top income and corporate
tax brackets can backfire on the economy. That's why their (non-VAT) tax
codes have moved closer to ours"
