The debate of the above issues offers a good context to discuss this second aspect: in the search for better conditions for achievement, what role does society assign to the Nation State?
In opposition to the old nationalisms inherited from the romantic period, the interaction with other nations is today a way of searching for solutions that earlier appeared to have a too impeccable national nature. As an example, we have seen that closed economies are relatively inefficient, since many production areas lack adequate resources. Opening up to other economies in these instances, should allow them to obtain better results with lower level of resources expenditure. We come once again to the Ricardian theory.
