**1. Introduction**

Well-being depends more and more on human development, given the ability of nations to promote investments capable of providing care, training and employment to citizens. The ability to guarantee free and efficient healthcare, education, training and work services to a large proportion of the population free of charge, or at least with limited costs, constitutes not only the concrete principles and base level of civilisation, but is, in fact, a prerequisite for the system to be competitive, functional and capable of generating wealth. The paradigm of the new millennium, as supported by the Fourth Capitalism dimension, requires that social development and economic grown be held together. The magnitude of the recent Covid 19 health

crisis has illustrated the importance of the relationship, showing how the level of human development is capable of determining the level of resilience within a given system, and how the ability to deal with crises, while crucial, is not sufficient. One the one hand, we have seen how countries in which economic growth and social development are not well integrated, matched with a higher level of inequality, such as the United states and Brazil, have struggled to deal with the consequences brought about by Covid 19. On the other hand, we have also seen how the impact of the large-scale health crisis is greater in regions and territories which a have a higher level of economic and human development, matched with a greater urban concentration and higher levels of pollution, mobility and traffic. The social dynamics determined by the Covid 19 pandemic have made the importance of a system capable of taking care not only of the disease, in terms of functioning hospitals and health centres, but of the social and welfare repercussions even more apparent. Addressing the various forms of malaise and discomfort through a network of social inclusion and assistance when it comes to welfare, accompanying and following people throughout the course of treatments. The Covid 19 health crisis helps to shed light on the contradictions present in contemporary society, showing how the road to a prosperous economy passes through social equality, sustainable development and a quality of life that supports the intertwined relationship between these two underlying principles in an attempt to combat against the main factors of discomfort in today's society, loneliness and lost ties [1–3].
