I think you are combining two separate points here. You are talking, at least as I understand it, about the costs of rebuilding, or new building in places where the particular facility had not been built before. This has nothing to do with Haiti ceding their sovereignty to the US, except that it may make the money more easily forthcoming.

I was going to add some other points here about 1st world privilege - to extend upon the prevalent theme in AE's blog of late - but I really don't have the knowledge of Haiti to make those points in this particular case.
