interesting idea

You may be interested in a paper by Napier and Jost, which makes a similar argument in explaining why conservatives are happier than liberals. Here is the abstract:

"In this research we drew on system justification theory and the notion that conservative ideology serves a palliative function to explain why conservatives are happier than liberals. Specifically, we found in three studies using nationally representative data from the U.S. and nine additional countries that right-wing (vs. left-wing) orientation is indeed associated with greater subjective well-being and that the relationship between political orientation and subjective well-being is mediated by the rationalization of inequality. In our third study we find that increasing economic inequality (as measured by the GINI index) over the past 30 years has exacerbated the ideological gap with respect to happiness, apparently because conservatives (but not liberals) possess an ideological buffer against the negative hedonic effects of economic inequality."
