Abstract
The author raises doubts about a sense of "catching up" and an idolatry of HDP's growth. His argumentation is based on the longitudinal international research of the link "economics-happiness" at the frontier between economics and psychology.
The rationality of economic science "more is better" is bounded by environmental and relational externalities: it is just what a "theory of happiness" argues against a "joyless economy". The family-household is an old istitution esp. loosing in a competition with the market economy.
The article stresses a role of "relational goods" explaining why more is sometimes less. The loss of happiness in market democracies (R.Lane) is the reason for a crisis of economic paradigm; it has a chance to be healed by a switch from the principle of imperial equivalence to a reciprocity (economy of communion).
Implications for economic policies based on a "science of happiness" reverse the link "economics-happiness" making from HDP growth a by-product of our effort for happiness.
