It's not that we didn't care but it's more like it's not our problem. Most African countries has corrupted governments and aids of any kind will only go to fat cats on the top.
The few that has managed or be managed properly has seen very good result:

A friend of mine has been thru Africa in the 90 is various Canadian gov initiatives to "help". It's not helping them one bit because the people and government are not set up to keep what they are given. Whatever infrastructure you set up, it'll be gone in weeks/months/years and people and militia strips it.
The key to get people out of trouble is the people to understand what happens when a government destabilizes and unable to enforce shit.
