In the year 2000, having narrowly escaped the Y2K computer glitch, Americans should have been poised to party. The bendy riff of the Santana–Rob Thomas joint “Smooth” wailed from Top 40 stations everywhere. Survivor beckoned us to watch people eat grubs for a chance at $1 million. Brad and Jen got married, and the gladiator Maximus Decimus Meridius asked acerbically, “Are you not entertained?”
But we weren’t. In fact, after chugging along steadily for decades, American happiness began to decline that year, modestly but definitively. A chart of American happiness ratings looks like this: a flat, basically happy line that starts in the 1970s, followed by a plunge into meh right around the new millennium.
