The people in Africa were panning for tiny particles of gold to feed their families.

It actually has happened and is probably still happening. Look up the YT videos on it. The situation was very sad. :(

But there are a lot of good stories too when people get some hope and realize they don't have to wait for the government or the Americans to come and save them.
