Society cant function when the population is divided  Successful nations are those with a strong unified sense of purpose. They are states where it is allegiance to the state which is put first. Having different identities which are put first undermines the state. This is exactly what strong religious and ethnic identities do. If these sub state identities are put before the national identity then ethnic groups are likely to “other” anyone who is not a part of their group. If they do not consider themselves as being a part of the same polity there is little reason to cooperate, to pay taxes,  It is the failure to build a unifying framework and these conflicts of identity that split nations apart not poverty. The Rwandan genocide did not happen because Rwanda is poor but because it is split between two groups who, at least for that horrific period, looked at themselves as Hutus or Tutsi’s first and Rwandans second. The rebels in Syria show how strong such divisions can be as rebels fight each other as well as Assad’s regime.(1) In Ivory Coast a country that had previously been considered stable burst into civil war in 2011 after elections that went along ethnic lines.(2)  (1) Dettmer, Jamie, “Syrian Rebel Groups Fight Among Themselves”, Voice of America, 19 September 2013   (2) “African viewpoint: Blood and borders” BBC News, 1 February 2011,
