Why, there is no evidence of that for straight people. Anything you point to deals with monogamy not the actual institution of marriage. What studies have been done?
Actually studies have been done based on marriage, not sexual orientation.
Charlotte A. Schoenborn, "Marital Status and Health: United States, 1999-2002," Advance Data from Vital and Health Statistics, Centers for Disease Control and Prevention (Number 351, December 15, 2004) is a good start to read on marriage positively effecting emotional and physical health. Obviously, if people are emotionally and physically healthier, they are less of a drain on society. It also shows married people drink and smoke less. All of these things are true regardless of any other criteria (age, race, etc) you put on the study.
Linda J. Waite and Maggie Gallagher, The Case for Marriage: Why Married People Are Happier, Healthier, and Better Off Financially (New York
oubleday, 2000) 50-52. This will tell you married people commit suicide at a much lower rate. Pages 97-123 break down income, and show married people are likely to be of higher income (more tax money, less of a drain).
Married people are more likely to vote, get involved in civic organizations, and be more involved in their local churches. See Corey L.M. Keyes, "Social Civility in the United States," Sociological Inquiry 72 (2002): 393-408, as cited in The Family in America New Research, November 2002. Also, Carl L. Bankston III and Min Zhou, "Social Capital as Process: The Meaning and Problems of a Theoretical Metaphor," Sociological Inquiry 72 (2002): 285-317, as cited in The Family in America New Research, December 2002.
I can go on and on, but, you get the picture.
2 parent household, well that is monogamy not marriage, stable household, again monogamy.
Monogamy is the benefit to society so since gay couples are already doing that there is no valid reason to not call it a marriage.
Please provide the studies that show monogamous cohabitation provides the same as marriage. The studies cited above (most of them) compare against monogamous cohabitation, and that falls short of marriage.
