In the name of the fight against terrorism, the United States is currently waging “credit-card wars” in Afghanistan, Iraq, Syria, and elsewhere. Never before has this country relied so heavily on deficit spending to pay for its conflicts. The consequences are expected to be ruinous for the long-term fiscal health of the U.S., but they go far beyond the economic. Massive levels of war-related debt will have lasting repercussions of all sorts. One potentially devastating effect, a new study finds, will be more societal inequality.
In other words, the staggering costs of the longest war in American history — almost 17 years running, since the invasion of Afghanistan in October 2001 — are being deferred to the future. In the process, the government is contributing to this country’s skyrocketing income inequality.
Since 9/11, the U.S. has spent $5.6 trillion on its war on terror, according to the Costs of War Project, which I co-direct, at Brown University’s Watson Institute for International and Public Affairs. This is a far higher number than the Pentagon’s $1.5 trillion estimate, which only counts expenses for what are known as “overseas contingency operations,” or OCO — that is, a pot of supplemental money, outside the regular annual budget, dedicated to funding wartime operations. The $5.6 trillion figure, on the other hand, includes not just what the U.S. has spent on overseas military operations in Iraq, Afghanistan, Pakistan, and Syria, but also portions of Homeland Security spending related to counterterrorism on American soil, and future obligations to care for wounded or traumatized post-9/11 military veterans. The financial burden of the post-9/11 wars across the Greater Middle East — and still spreading, through Africa and other regions — is far larger than most Americans recognize.
"Our examination of the future of public debt leads us to several important conclusions. First, fiscal problems confronting industrial economies are bigger than suggested by official debt figures that show the implications of the financial crisis and recession for fiscal balances. As frightening as it is to consider public debt increasing to more than 100% of GDP, an even greater danger arises from a rapidly ageing population. The related unfunded liabilities are large and growing, and should be a central part of today's long-term fiscal planning. "It is essential that governments not be lulled into complacency by the ease with which they have financed their deficits thus far. In the aftermath of the financial crisis, the path of future output is likely to be permanently below where we thought it would be just several years ago. As a result, government revenues will be lower and expenditures higher, making consolidation even more difficult. But, unless action is taken to place fiscal policy on a sustainable footing, these costs could easily rise sharply and suddenly. "Second, large public debts have significant financial and real consequences. The recent sharp rise in risk premia on long-term bonds issued by several industrial countries suggests that markets no longer consider sovereign debt low-risk. The limited evidence we have suggests default risk premia move up with debt levels and down with the revenue share of GDP as well as the availability of private saving. Countries with a relatively weak fiscal system and a high degree of dependence on foreign investors to finance their deficits generally face larger spreads on their debts. This market differentiation is a positive feature of the financial system, but it could force governments with weak fiscal systems to return to fiscal rectitude sooner than they might like or hope. "Third, we note the risk that persistently high levels of public debt will drive down capital accumulation, productivity growth and lon
