Whenever dealing with disasters, we must always use subsidiarity! Without it, we risk destroying economies, as the US and others have done in Africa.
A major Haiti government official, says BBC, has warned that food aid possibly threatens the Haitian economy. This is a very real, and connected fear. What is given free affects what is sold. What is sourced in foreign nations, affects that made locally.
The solution: source locally, that is that! CRS and Caritas often have, as has the World Food Program recently in Africa to my knowledge.
