In Western countries three main visions confront each other:
- The neoliberal one, that focuses on market forces in order to bring people prosperity and security;
- The neonationalist one, of which a main element is the concept of the Nation-State and its components: protection, unity and competitiveness; and
- The globalised one, that tends to instate regulation mechanisms according to human values, such as individual responsibility, or equal rights and chances.
This last vision - that was developed after World War II - is mainly promoted by the United Nations and other international organisations, as it seems to be the only one assuring a viable and bearable world for each of us. In this approach, sustainable development is one of the main concepts appropriate to apprehend our world.
