But there is one change that, over time, could reverse the problems that have built up over the last few decades. We should have mandatory military service for all Americans, men and women alike, when they turn 18. The idea is radical, unlikely and impractical but it just might work.
There is no better explanation for what has gone wrong in Washington in recent years than the tabulation done every two years by the American Legion counting how many members of Congress served in the military.
A Congressional Quarterly count of the current Congress finds that just 86 of the 435 members of the House are veterans, and only 17 of 100 senators, which puts the overall rate at 19 percent. This is the lowest percentage of veterans in Congress since World War II, and down from a high of 77 percent in 1977-78, according to the American Legion. For the last 21 years, the presidency has been occupied by men who didn't serve or, in the case of George W. Bush, served in a capacity designed to avoid combat.
It's no coincidence that this same period has seen the gradual collapse of our ability to govern ourselves: a loss of control over the nation's debt, legislative stalemate and a disabling partisanship. It's no coincidence, either, that Americans' approval of Congress has dropped to just 9 percent, the lowest since Gallup began asking the question 39 years ago.
Because so few serving in politics have worn the uniform of their country, they have collectively forgotten how to put country before party and self-interest. They have forgotten a "cause greater than self," and they have lost the knowledge of how to make compromises for the good of the country. Without a history of sacrifice and service, they've turned politics into war.
Compulsory military service, as old as Athenian democracy and common in countries such as Israel that live under threat, has been in decline in Western Europe since the end of the Cold War. But an exception, Switzerland, is instructive: On Sept. 22, the Swiss voted 73 percent to 27 percent to keep their conscription army. It has less to do with security than with national identity in a land of 26 cantons and four official languages. The government argued that military service teaches people "how to live and work with compatriots from all regions, all linguistic groups and all social strata," which "contributes enormously to the national cohesion."
In Switzerland, the sons of bankers and farmers alike do basic training for several months and then are recalled to service for brief periods. But the structure is less important than the service itself. My former colleague Tom Ricks proposes bringing back the draft in the United States but allowing for a civilian national service option teaching, providing daycare, and the like for those who don't want to join the military.
There's no mass movement for mandatory service, but the idea has gained a diverse group of supporters, including retired Gen. Stanley McChrystal and Rep. Charlie Rangel, D-N.Y. Gun-rights groups would cheer an armed citizenry, and an article published by the libertarian Cato Institute argued that compulsory service "can be a pillar of freedom."
The costs would be huge. But so would the benefits: overcoming growing social inequality without redistributing wealth; making future leaders, unlike today's "chicken hawks," disinclined to send troops into combat without good reason; putting young Americans to work and giving them job and technology skills; and, above all, giving these young Americans a shared sense of patriotism and of service to the country.
It would take some time, but this new generation of Americans, once again asking what they can do for their country, would undo much of the damage today's crop of self-interested leaders is doing to our politics.
