I think it's naive to attribute all of the world's problems to "misinformation". You can give everyone the same information; in fact, we all already have the same information. But perspectives will vary, and there will be conflict.
This is an interesting premise, but I don't think it really holds up. The world is absolutely too complex for any of us to understand everything, but this is not a problem. You can abstract everything away to 'black boxes', and there are always a few people that understand what's going on in those 'boxes'.
