This obviously reflects the component of cognitive competence. This is again a form of material competence. Social inequality implies less control for those who are in the weaker position, and more risks of losing their privileges for those in the stronger position. This directly reflects the strong correlation between happiness and biological fitness. This reflects what we have called subjective competence.
Happy people are also more psychologically resilient, assertive, empathetic and open to experience.
This reflects the degree to which people manage to satisfy their social needs, and get better control of their own situation by relying on the support of others. Occupationally, happiness tends to be more common among professionals and managers, that is, people who are in control of the work they do, rather than subservient to their bosses. These events on their own signal the success or failure to reach one's goals, and therefore the control one has. In conclusion, although these observations cannot prove that perceived competence to satisfy needs is necessary and sufficient for happiness, they do confirm the basic tenets of the evolutionary-cybernetic theory of happiness. Moreover, they clarify how happiness can be promoted in practice, namely by the promotion of wealth, education, freedom, equality, health, personal control, self-actualization and intimate relations.
