Haiti has needed help for many generations. That it needs help again is not anything new. And help with the current crisis will be next to useless without a massive multi-decade multi-generational infusion of leadership, money, infrastructure repair, ecological education, health maintenance, education, etc, etc, etc, ----- Haiti is a mess and has been for a long, long time.

Perhaps the Vatican can supply the above listed items for this, an overwhelmingly Catholic populated nation. It would be corporal and spiritual acts of mercy acted out for the world to see. The RCC surely has the funds and, I suspect, the means to access the needed expertise. 

I am not in favor of benevolent dictatorships or church/state coalitions, but either or both might be Haiti's only way out of their mess.
