If all there was to go on were sitcoms, movies, and mainstream editorials, we’d have to conclude that marriage is a direct path to misery, the “old ball and chain” that only ties us down, limits our freedom, and cramps our sexual fun. Many people now think of marriage less as “settling down” and more as “settling.” Young people are told, “You’ve got plenty of time, live a little, first,” as if life ends after the wedding.The truth about marriage, however, is that it is, statistically, the single best predictor of long-term happiness. Making this even more important to understand is that for at least the last 20 years now, Americans have been steadily getting lesshappy.
