Over on Evangel, Gayle Trotter has an interview with Bryan Caplan , professor of Economics at George Mason University, about his new book, Selfish Reasons to Have More Kids: Why Being a Great Parent Is Less Work and More Fun Than You Think . Throughout the book, Caplan shows that the “price” of high-quality kids is less than parents imagine. Then he asks and answers the question, “What does enlightened self-interest tell you to do when you find out that something is cheaper than you previously believed? Buy more.”
