Thus, the potential for a Sociology of Happiness is there, and it is increasingly being exploited. Valuable emerging approaches to connect sociological theory with SWB include Brockmann’s analysis of age and SWB (2010), studies of postmodern values and SWB by Delhey (2010), or Inglehart & Welzel (2005), as well as the many contributions by Veenhoven. In fact, according to the latter author, studies on life satisfaction and happiness address questions that lie at the heart of sociology, as “subjective wellbeing is both an outcome of social systems and a factor in their functioning. As such the subject belongs to the core business of sociology” (Veenhoven, 2008: 58). Finally, George (2010) recently claimed to have identified four groups of evolving theoretical schools in SWB research: discrepancy theories, social comparison, strategic investments of resources, the social stratification of SWB, and the social indicators perspective. These five classifications can be considered to contain (at least partly) a sociological argumentation.
