This Fast Company article asks an important question: Do some charities have a shelf-life? Is it possible that some of them need to shut down after they've accomplished their mission—or given it an honest shot that didn't work?
Though the article doesn't quite get there in any substantial way, the key question for me is more a matter of who gets to decide such things and whether or not we should make those decisions.
Do we need to cull the herd like a game warden who sees how too many of one species threatens the ecosystem? Are we in a position to actually understand the when, why, and how dynamics of setting the noose?
Is there a role for active agency in deciding when to time-of-death for a charitable organization?
