TBH I think many people become wearied of situations that are largely self-inflicted, because of tribal/religious/political factions endlessly warring among themselves. Because however much aid is poured in, until these warlords stop, nothing much is ever going to change.
Natural disasters such as earthquakes, typhoons, famine caused by drought, IMO often evoke a different response.
A dd has worked for many years for major NGOs, so I’ve probably heard more than many people of bribery and corruption*, not to mention govts. formed largely of wealthy elites who don’t give much of a toss (if any) about their own people.
*One case I particularly remember was shortly after the 2004 tsunami in Aceh, Indonesia. Because of the scale of the disaster, many roads were simply impassable without 4WD vehicles, which made distributing aid to so many people impossible. So the NGO dd worked for shipped some such vehicles in.
Customs officials refused point blank to release them without payment of hefty bribes. And the NGO in question had a strict policy of never paying bribes, so the vehicles had to sit there for some weeks until - eventually - someone higher up deigned to intervene.
