Remittance is not change. Remittance is sending water bottles to a people inside of a burning building.
Has nothing to do with investing politically, educationally or socially.
Schools, hospitals, and businesses get funded as well. The scale of what you're talking can't be done with an instable government and insecurity. Nobody's going invest in a business that's going to get robbed and or burned down. Money doesn't grow on trees. I've personally invested 100k in Haiti. And can't get off the ground because of the gang problems.
