Shall we look for a correlation between well-being (or ill-being) and inequality? How can we positively define, assess and promote well-being without falling into what sociologist Sam Binkley [author of "Happiness as Enterprise"] defines as the ultimate step into the neoliberalisation of the self? 

Inequality and ill-being go hand in hand, and this is even more evident if well-being is not seen just from a subjective perspective. Prof. Perri 6 pointed out "well-being is something that we do together, not something that we each possess". 

Richard Layard reminded us in his book "Happiness, lessons from a new science", we cannot just consider an aggregate value of well-being as a measure of societal progress. A "life worth living" can be promoted  by policies targeted to reduce inequality that may have an impact on current patterns of wealth distribution. How much of this can be achieved will depend also on how far we can cultivate each other well-being. Much of it will happen in urban areas that should offer spaces and opportunities for this mutual, social creation of well-being to occur.
