Check out this article reporting research by the Pew Research Center which shows that the happiest people are old, male, and Republican - in other words, me! Imagine - this occurs during a time when the national political agenda is controlled by Democrats.
And guess what, Republicans aren't happier because they are richer. Even when researchers control for income Democrats are just less happy, as are women. One could draw all sorts of speculative conclusions from this data, have fun with it.
