The road back from failed statehood for Haiti is long and currently blocked by monumental political and social landslides of epic proportions.
No one in their right mind apart from despots who have no compunction pillaging even more from a country and its people are even interested in holding political office. The shear magnitude and time frame required to address all that ails Haiti is Herculean.
Resetting Haiti requires:
A motivated and willing ruling class
A motivated and willing general population
A robust plan of action set in stone spanning the next 20 to 30 years.
Money
Haiti has no more riches that are of interest to foreign countries, just piles of problems and debt. Few companies are even interested in operating there apart from a few who see potential profit from patchwork infrastructure service contracts that even the despots can't deny being required just to keep their pockets from emptying completely. There is insufficient political will and insufficient public determination to see any sort of sustained effort over the time period required. With an economy that barely meets the minimum requirements of such, there is no way to capitalize all that needs to be done to turn that state around from within even if the will and expertise were in place.
From a purely humanitarian point of view, Haiti needs to be taken over, the current govt shut down and all of the functionaries dismissed. An appointed administrative entity will replace the democratic govt for at least a generation. An external coalition of nations would then need to completely fund the rebuilding of the country to the point that there is a functioning and expanding economy, life sustaining infrastructure is robust and reliable, and every citizen is given a job to establish pride in their circumstances and a real stake in their country again. There needs to be an army of people replanting hundreds of millions of trees and those who can do nothing else, can at least be put to work doing this.
There is no foreign interest in long term direct intervention of the magnitude required to save Haiti from itself and the Haitians do not have the where-with-all to do this themselves. There is no hope for Haiti as it exists today, just more corruption, squalor and the ongoing depletion of what little resources and opportunity remain today, by those who see themselves entitled to take it.
