Prediction :
Itachi's goal is 100% different than Akatsuki's world domination goal.
There's no reason itachi wouldnt be the leader unless he had some other kind of plot that he was just using the akatsuki for.
No idea what he really wants to do...but i doubt it has anything to do with money/ world domination
Maybe Itachi is going to attmpt to become a demon, Or he wants to use the sharingan to steal the chakra from all the tails-demons.
