Haitians on the payroll helps Haiti regardless where the factory is located. Jobs on the border slow down economic refugees. Those who go to the border and don't find jobs is no reason to not put a free zone there.The investment has to be in Haiti for the government over there to be an issue at all. The fact is that most of the factories are on the DR side of the border while using an overwhelmingly Haitian workforce. I wish people would use an actual map instead of Google Maps and notice that the Dajabon River is in most area at the border and in some area to the east of the border. At no point in the Dajabon province does some land east of the river is part of Haiti. Google Maps show the factories to be in Haiti when they are not.
The other issue is what will be done with all the other Haitians who will move to the border from many areas of Haiti looking for their piece too and not find it? The border is so close by and in most areas wide open and porous.
