While Palestinian refugees benefit materially from UNRWA, the agency benefits in return from the refugees. The refugees are the organization’s raison d’etre. And bureaucracies tend to dislike dissolving themselves. So, like any good bureaucracy, UNRWA has zero incentive to resolve the Palestinian refugee problem if it is to continue to exist. Ending the refugee problem would render UNRWA obsolete. http://www.meforum.org/article/1807
