If everyone was well-fed, had access to quality education, power supply, clean water and a decent standard of living, who would think of trying to kill off another religious/ethnic group seen to be "competing for space"? 
Ikiwa kila mmoja angekuwa ameshiba, angekuwa na uwezo wa kupata elimu nzuri, umeme, maji safi na hali nzuri ya maisha, nani angefikiria kujaribu kuliua kundi jingine la dini/kabila ambalo linaonekana “kupigania nafasi”?
