Yes and that's a stupid point. Again, it's like looking at the life outcomes of lotto winners and concluding the lottery is actually a hinderance. Shit countries have oil and surprise, they manage to waste that resource. That doesn't mean the resource is a hindrance though.
This is the problem I have with your whole menatality. Because some can't properly manage what amounts to free wealth all of a sudden that wealth is a bad thing? how about you keep reading Sachs and I'll just take the oil.
