Dennis Prager has some ideas.
The unhappy gravitate toward the left… Life is hard for liberals, and life is hard for conservatives. But conservatives assume that life will always be hard. Liberals, on the other hand, have utopian dreams. At his brother Robert’s funeral, the late Sen. Edward M. Kennedy recalled his brother saying: “Some men see things as they are and say ‘why?’ I dream things that never were and say ‘why not?'”
Utopians will always be less happy than those who know that suffering is inherent to human existence. The utopian compares America to utopia and finds it terribly wanting. The conservative compares America to the every other civilization that has ever existed and walks around wondering how he got so lucky to be born or naturalized an American.
The liberal in Minnesota grouses himself into incontinence over LGA cuts, and works himself into a froth over how much “Better” a Minnesota we’d have if everyone else was just paying more money.
Third, imagine two Americans living in essentially identical socioeconomic conditions. Both earn $45,000 a year, both have the same amount of debt on their homes and both have the same number of dependents. One seeks governmental assistance wherever possible; the other eschews any governmental help. Which one is likely to be the liberal and which one is likely to be the happier individual?
This is not a question only an oracle can answer. The one who yearns for governmental help is the one who is likely to be both liberal and less happy. Conservatism, which demands self-reliance, makes one happier. The more one feels that he is captain of his or her ship (as poor as that ship may be), the happier he or she will be.
