Anti-tax advocates insist that we should cut taxes even more to boost a flagging economy—an argument that hits the news cycle nearly every hour and that will shape the coming TV "debate." As the New York Times recentlynoted, however, tax cuts might have been effective in giving the economy a lift decades ago when tax rates were above 70%. (And no, that's not a typo, that's what your parents and grandparents paid without much grumbling.) With effective tax rates around14% for Mitt Romney and many others, further cuts won't hasten job creation, just the hollowing out of public investment in everything from infrastructure to education. Right now, the negative effects of tax increases on the most well-off would be small—read: not a disaster for "job creators"—and those higher rates would bring in desperately-needed revenue. Tax increases for middle-class Americans should arrive when the economy is stronger.

Right now, the situation is clear: we're simply not paying enough to fund the basic ingredients of prosperity from highways and higher education to medical research and food safety. Without those funds, this country's future won't be pretty.

3. Neither the status quo nor a voucher system will protect Medicare (or any other kind of health care) in the long run: When it comes to Medicare, Mitt Romney has proposed a premium-support program that would allow seniors the option of buying private insurance. President Obama wants to keep Medicare more or less as it is for retirees. Meanwhile, the ceaseless rise in health-care costs is eating up the wages of regular Americans and the federal budget. Health care now accounts for a staggering 24% of all federal spending, up from 7% less than 40 years ago. Governor Romney's plan would shift more of those costs onto retirees, according to David Cutler, a health economist at Harvard, while President Obama says the federal government will continue to pick up the tab. Neither of them addresses the underlying problem.

Here's reality: Medicare could be significantly protected by cutting out waste. Our health system is riddled with unnecessary tests and procedures, as well as poorly coordinated care for complex health problems. This country spent $2.6 trillion on health care in 2010, and some estimates suggest that a staggering 30% of that is wasted. Right now, our health system rewards quantity, not quality, but it doesn't have to be that way. Instead of paying for each test and procedure, Medicare could pay for performance and give medical professionals a strong incentive to provide more efficient and coordinated care. President Obama's health law actually pilot tests such an initiative. But that's another taboo topic this election season, so he scarcely mentions it. Introducing such change into Medicare and the rest of our health system would save the federal government tens of billions of dollars annually. It would truly preserve Medicare for future generations, and it would improve the affordability of health coverage for everyone under 65 as well. Too bad it's not even up for discussion.

4. The US military is outrageously expensive and yet poorly tailored to the actual threats to US national security: Candidates from both parties pledge to protect the Pentagon from cuts, or even, in the case of the Romney team, to increase the already staggering military budget. But in a country desperate for infrastructure, education, and other funding, funneling endless resources to the Pentagon actually weakens "national security." Defense spending is already mind-numbingly large: if all US military and security spending were its own country, it would have the 19th largest economy in the world, ahead of Saudi Arabia, Taiwan, and Switzerland. Whether you're counting aircraft carriers, weapons systems, or total destructive power, it's absurdly overmatched against the armed forces of the rest of the world, individually or in combination. A couple of years ago, then-Secretary of Defense Robert M. Gates gave a speech in which he detailed that overmatch. A highlight: "The US operates 11 large carriers, all nuclear powered. In terms of size and striking power, no other country has even one comparable ship." China recently acquired one carrier that won't be fully functional for some time, if ever—while many elected officials in this country would gladly build a twelfth.

But you'll hear none of this in the presidential debates. Perhaps the candidates will mention that obsolete, ineffective, and wildly expensive weapons systems could be cut, but that's a no-brainer. The problem is: it wouldn't put a real dent in national defense spending. Currentlyalmost one-fifth of every dollar spent by the federal government goes to the military. On average, Americans, when polled, say that they would like to see military funding cut by 18%.

Instead, most elected officials vow to pour limitless resources into more weapons systems of questionable efficacy, and of which the US already owns more than the rest of the world combined. Count on one thing: military spending will not go down as long as the US is building up a massive force in the Persian Gulf, sending Marines to Darwin, Australia, and special ops units to Africa and the Middle East, running drones out of the Seychelles Islands, and"pivoting" to Asia. If the US global mission doesn't downsize, neither will the Pentagon budget—and that's a hit on America's future that no debate will take up this month.

5. The education system is what made this country prosperous in the twentieth century—but no longer: Perhaps no issue is more urgent than this, yet for all the talk of teacher's unions and testing, real education programs, ideas that will matter, are nonexistent this election season. During the last century, the best education system in the world allowed this country to grow briskly and lift standards of living. Now, from kindergarten to college, public education is chronically underfunded. Scarcely 2% of the federal budget goes to education, and dwindling public investment means students pay higher tuitions and fall ever deeper into debt. Total student debt surpassed $1 trillion this year and it's growing by the month, with the average debt burden for a college graduate over $24,000. That will leave many of those graduates on a treadmill of loan repayment for most or all of their adult lives.

Renewed public investment in education—from pre-kindergarten to university—would pay handsome dividends for generations. But you aren't going to hear either candidate or their vice-presidential running mates proposing the equivalent of a GI Bill for the rest of us or even significant new investment in education. And yet that's a recipe for and a guarantee of American decline.

Ironically, those in Washington arguing for urgent deficit reduction claim that we've got to do it "for the kids," that we must stop saddling our grandchildren with mountains of federal debt. But if your child turns 18 and finds her government running a balanced budget in an America that's hollowed out, an America where she has no chance of paying for a college education, will she celebrate? You don't need an economist to answer that one.
