They claim that if a state is in a good economic period and has strong control over its population, the clans will simply weaken the institutions of said state. Even clans that do not have the privilege of having access to government will begin to harbor long-standing resentments towards clans that do. (Collins Kathleen. 2004) The process becomes unsustainable when the state is weak or has failed to establish economic prosperity. Under these circumstances, the pressure on clan leaders to provide for their members increases dramatically. This leads to rapid deprivation of state and natural resources by politically high-ranking clan members in an attempt to secure such resources for their clans. (Collins Kathleen. 2004) These clans then use the newly received resources to consolidate their power and fortify the areas they control. This leads to a decentralization of power and an eventual emptying of state coffers. These new power centers of clan leadership can now extract nothing else from the state, so they turn to each other through an informal regime of clan bargaining. (Kathleen Collins.
