As we search for paths out of America’s economic crisis, many suggest business as a paradigm for cutting costs. According to my back-of-the-envelope math, top C.E.O.’s earn as much as $1 a second around the clock, partly by cutting medical benefits for employees. So they must be paragons of efficiency, right?

Actually, I’m not so sure. The business sector is dazzlingly productive, but it also periodically blows up our financial system. Yet if we seek another model, one that emphasizes universal health care and educational opportunity, one that seeks to curb income inequality, we don’t have to turn to Sweden. Rather, look to the United States military.

You see, when our armed forces are not firing missiles, they live by an astonishingly liberal ethos — and it works. The military helped lead the way in racial desegregation, and even today it does more to provide equal opportunity to working-class families — especially to blacks — than just about any social program. It has been an escalator of social mobility in American society because it invests in soldiers and gives them skills and opportunities.

The United States armed forces knit together whites, blacks, Asians and Hispanics from diverse backgrounds, invests in their education and training, provides them with excellent health care and child care. And it does all this with minimal income gaps: A senior general earns about 10 times what a private makes, while, by my calculation, C.E.O.’s at major companies earn about 300 times as much as those cleaning their offices. That’s right: the military ethos can sound pretty lefty.
