Yes so much dependence on government to provide everything is one major issue. If given the opportunity, youths will be made to acquire skills that will make them self dependent. It's said that an idle mind is the devil's workshop.
Most criminal activities that are done under ethnicity when properly viewed are aimed at satisfying one or two individuals needs of the criminals which clearly shows that no ethnic group teams up against another all things being equal.
To me, once most people especially youths are gainfully engaged, the ethnic divides will naturally die.
