While preserving problems is undoubtedly a natural incentive, I think Hanlon's razor applies here. Just today I was reading Competent Bureaucracy - Rebuilding State Capacity (<https://cdn.sanity.io/files/d8lrla4f/staging/cf7eedaf5d21d27...>) on the topic of agency structure promoting success (the author has done a nice amount of work in the past - e.g. https://www.statecapacitance.pub into this history of this topic).
Pournelle’s Iron Law of Bureaucracy: every organization has two groups of people. The first group cares about the organization's main goal. The second group cares about the organization itself. Group two always wins, takes control, and writes the rules.
So NGO’s go from combating homelessness to being the organization about homelessness.
I sometimes think organizations should be set up with hard end dates. At which point the organization is disbanded and resources redistributed. If the problem still exists a new ord should be created with a new scope and new timeline.
