I don't know the story about the picture at hand. However it's not as simple as having the resources to fix the bridge. These people are most likely dealing with Warlords who wouldn't allow anything to be fixed etc. A lot of these 3rd world countries are living in shit not because its people won't rise up, but the Warlords are being supported by 1st world countries. Some people just never have a chance. Free will is an illusion.
