Before I return to the single-payer health care proposal in California, here is another matter that fits into the same narrative (exactly how will be explained later). It is a proposal for how to shield defense spending from the ups and downs of the federal budget, as well as from short-term political, partisan preferences.

While
many government functions fill important needs in people’s lives, some of those
functions are more important than others. It is essential to protect those
functions from the booms and busts of the business cycle. The need to protect those
programs is further elevated under a balanced-budget amendment: in recessions
when tax revenue is tight, limited borrowing capacity leads to tough priorities
- or sequester-style across-the-board spending cuts.
Social Security is of major importance, not just to
Democrats in Congress, but to Republicans as well as millions of Americans
whose daily livelihood depend on the program. It has, over time, become as
essential to our nation as defense spending. Thanks to its independent funding
mechanism, it is to some degree shielded from the annual swings in
Congressional fiscal policy. This does not mean the program is solvent for the
foreseeable future – quite the contrary – but there is a great deal of common
sense to the basic idea of an independent funding arm for the program.
Defense spending, again, is also essential. Given the major
role that the U.S. armed forces play not just for our nation, but globally, it
is important to secure its funding for the future. Specifically, Congress
should develop a funding model that protects the Department of Defense from
disruptive, sequester-driven cuts.
One way to make defense spending immune to sequester cuts is
to develop a funding model mimicking Social Security. Tax revenue can be
guaranteed by a dedicated Defense Tax. Since 80 percent of federal tax revenue
comes from taxes on personal income, it is reasonable to carve out a share of
those tax revenues and dedicate them as a tax specifically set aside for
national defense. The tax could consist of the first dollars of a person’s
federal tax liability. For example, if a person owes $2,000 federal income
taxes, and the Defense Tax would be 20 percent of a person’s federal tax
liability, then the first $400 that the taxpayer pays for that year would go
unabridged to funding national defense.
Once the Defense Tax was paid, the rest of the personal
income tax revenue would go toward general-fund expenditures. The share going
to the Defense Tax would vary based on a mechanism described in Equation 1
below.
Reasonably, the Defense Tax should be governed by no other
factor than the global geo-political and other factors taken into account when
Congress determines the defense budget. Ideally, this would require a forecasting
mechanism to provide Congress with a formula for setting the Defense Tax.
However, the past quarter century has proven that such forecasting is very
difficult. The end of the Cold War and the collapse of the Soviet Union and its
satellite states redrew the global map in more ways than one. The 9/11 attacks
led to a fundamental transformation of the Middle East, with repercussions as
far away as Tunisia and Africa’s Horn. In the past few years, the economic and
political erosion of the European Union has led to instability, uncertainty and
shifting political alliances on a continent often regarded as the epitome of
political, social and economic stability.
With these experiences on record, it is more prudent to base
a Defense Tax not on forecasts of future military needs, but on a trend in
historic defense spending. As an experiment, the consider the following equation:
where TD
is the total revenue from the Defense Tax in one year, the sigma numerator is the sum total of defense spending over the
past five years, and M is a mark-up
coefficient. Equation 1 thus determines the current-year Defense Tax as the
average of defense spending over the past five years, multiplied by a mark-up.
The mark-up is important. It brings past spending up to
current levels in terms of inflation and technological progress. It means,
simply, that this year’s Defense Tax will be 20 percent higher than the average
for the past five years.
By tying the Defense Tax to past defense spending in this
manner, Congress takes a big step toward independence in the funding of
national defense. There is just one more step needed.
Equation 1 provides stability and progress in defense
funding, but it does not in itself allow for contingencies that require rapid
increases in defense spending. The response to the 9/11 attacks would not have
been possible without extraordinary appropriations; if Congress must rely on
such mechanisms in times of rising international tensions or conflicts, then
defense funding will eventually be put alongside other budget items. That
defeats the purpose of the Defense Tax.
A Defense Trust Fund would guarantee full funding
independence for our national defense. It would have a simple construction:
whatever surplus there is from the Defense Tax when national defense has been
funded will be deposited into a fund. As that fund grows, it provides extra money
available on tap, should Congress determine that there is a need for a rapid
increase in defense spending. (To prevent frivolous spending increases, driven
by political concerns unrelated to national defense, it is appropriate to
attach a three-fifths majority threshold to any bill tapping into the Defense
Trust Fund.)
Figure 1 explains how the Defense Tax and the Defense Trust
Fund would have worked if they had been instituted in 1969. Actual national
defense spending numbers are used throughout. (The year 1969 is chosen based on
availability of appropriate data.)

The
build-up of defense spending under the Reagan administration would have tapped
into the Defense Trust Fund for several years, even led to a complete depletion
of the fund. This has to do with the starting point: in this simulation the
fund had not existed very long at that point. A similar depletion episode after
9/11 allows for a doubling of defense spending over a decade.
The depletion episodes could in theory be a matter of
concern. However, the construction of the Defense Tax is such that once defense
spending accelerates, the tax increases with a lag. This has three advantages:
1. The
drawdown of the Defense Trust Fund has a limit in time, ending when the Defense
Tax catches up with defense spending;
2. The
rise in the Defense Tax is gradual, saving the economy from rapid, disruptive
tax increases;
3.
The availability of the Defense Trust Fund
allows Congress to focus on the necessary defense build-up without getting
caught up in a political battle over tax policy in times of global uncertainty.
The construction of the Defense Tax also has a balancing
mechanism. When a period of global tensions is over and defense spending
flattens, or even decreases, the tax does the same in a lagged fashion similar
to its increase. This prevents excessive build-up of the Defense Trust Fund; as
the historic account above indicates, the money stored away in the fund will be
enough to allow for the reserve needed in times of national uncertainty.
