I have never heard of an African burial that failed because of poverty. So our dead always get buried by all means. What I am saying here is, there is no such thing like a failed burial. If anything, it may either be befitting or just normal. The thing is, all what is necessary for the burial is somehow made available, and not necessarily by close relatives.
The African burial is literally a communal responsibility and in such moments many give selflessly. Most relevant people find time and means to be present as we leave everything else and focus on the burial. This means, the goal is shared, approved and supported by everybody. More importantly, everyone understands what needs to be achieved, and nothing less is expected or allowed to happen.
