Explain why they have exploited the resources in african countries then and later on installed rulers who let this happens as long as their bank account gets fatter.
It's an agenda, Africa is the heart of the world it has been blessed with resources but is now being robbed.
Africa for Africans, slap these foreigners hands.
These "puppets" are Kings in their own countries.
Once placed they could turn around do whatever they want.
However it's their choice to continue this fuckery so we can't blame it on others.
Also the political class has already given up on their qashin population who wouldn't know what to do with development even if you served it up on a plate.
They don't see any chance that productivity per worker would go up so why bother looking for them for Riches?
Just ignore them altogether. Don't even tax them other than bribes for your gang/police to keep the order.
Just focus on land and your short term interests.
That's the unfortunate point of view most African leaders have.
