But cohabitation doesn't begin to confer the benefits that marriage does. In "The State of Our Unions," scholars associated with the Institute for American Values outline some of the advantages married couples enjoy over their single counterparts. "Men who marry," writes Alex Roberts, "typically earn more because marriage itself leads to increases in income; that is, men who marry work harder, work smarter, and earn more than their unmarried peers ... Cohabiting couples ... are less likely to pool resources, feel obligated to spend wisely and save, or invest in the future of the household." Married men earn between 10 and 40 percent more than their single counterparts with similar educational and job histories.
