The Pew survey reveals that nearly 40% of us think marriage is obsolete. This doesn't mean, though, that we're pessimistic about the future of the American family; we have more faith in the family than we do in the nation's education system or its economy. We're just more flexible about how family gets defined. Even more surprising: overwhelmingly, Americans still venerate marriage enough to want to try it. About 70% of us have been married at least once, according to the 2010 Census. The Pew poll found that although 44% of Americans under 30 believe marriage is heading for extinction, only 5% of those in that age group do not want to get married.
