There are very few things harsher and harder than living in a slum - extreme poverty, lack of even the basic infrastructure, lack of even the basest sanitation and the list goes on and on. Move that slum to Africa and the challenges literally quadruple (and, by the way, if you think there are no slums in Europe or in America, then I suggest travelling to Calais in France, Saint Barbara in Athens and many more). People who live in slums sacrifice everything simply to survive - education, hobbies, housing, jobs, prospects, sometimes even family - and at the end, they frequently simply die trying. Death rates (from multiple causes) within slums are more than 15 times higher than outside.
