Social conservatives have become more open to government spending if it encourages more women to have children and enables them to stay home with them. They cite research that children benefit from strong attachment to their parents. “The right has dropped the ball on family policy,” said Brad Wilcox, a sociologist at the University of Virginia, in a recent panel at A.E.I. where the divisions on the right were on full display. “I’m not looking for more measures that will put parents into the labor force than spend time with their kids. We need less workism and more familyism.”
