David Leonhardt strikes again. As he now seems to do with some regularity, he takes a complex body of work and reduces it to a soundbite, eliminating the complexity and uncertainty that underlies the research. His soundbite this time links two parent families to upward mobility, and notes that two different dynamics produce two parent families: high income and religion. He then replicates maps that purport to show these linkages.
