Christmastime is an occasion for families to come together. But the family is not what it used to be, as my former American Enterprise Institute colleague Nick Schulz argues in his short AEI book Home Economics: The Consequences of Changing Family Structure.

It’s a subject that many people are uncomfortable with. “Everyone either is or knows and has a deep personal connection to someone who is divorced, cohabiting, or gay,” Schulz writes. “Great numbers of people simply want to avoid awkward talk of what are seen as primarily personal issues or issues of individual morality.”
