As someone who is both a liberal and appalled at the cosmic unfairness of life, I found this article quite interesting:
Regardless of marital status, income or church attendance, right-wing individuals reported greater life satisfaction and well-being than left-wingers, the new study found. Conservatives also scored highest on measures of rationalization, which gauge a person's tendency to justify, or explain away, inequalities.
There was nothing really new in the thinking, I guess, it's more that it's disturbing to have scientific evidence backing up the idea that conservatives are happier because they're better at justifying life's unfairness. I mean, after all, how many rich conservatives have you heard offer excuses like "they're poor because they're lazy" or "I pulled myself up by my bootstraps, you can too!"
