Increased sense of identity with the state increases social solidarity.  Where groups of people do not identify with the state they are less likely to be willing to invest in more generous state services since they do feel that peoples with whom they have no affinity will benefit from them. Conversely, where people feel like the state is mostly composed of people like them, they are more willing to invest in education, healthcare and a welfare state. These things will ultimately significantly improve the lives of the people in each new state and lead to stronger states than the one that exists now. For example the Scandinavian states, Norway, Denmark, Sweden and Finland with their largely homogenous societies are also associated with very high levels of social happiness and generous welfare provision.
