Even before the earthquake, if God wanted to dump on the earth, Haiti would have been where he squatted.
Sounds crude, but it has been true for at least a Century, and Haiti has been the bane in one way or another of every single US President in my lifetime.
It would be cheaper to evacuate all of Haiti; let’s say to Cuba, and abandon that end of the Island of Hispanola for several generations.
Then start over.
I found a minor error in your:
“It would be cheaper to evacuate all of Haiti ...”
It would be more accurate as:
“It would be cheaper to depopulate all of Haiti ...”
Nobody wants Haitians. They took a prosperous island and turned it into a perfect example of Turd World degradation. That place is so nasty and degraded that even Elbonia looks good in comparison.
Think of Dogpatch but Daisy Mae is black and ugly. And may have Leprosy.
