I think that I should have expressed myself a little better.
Whilst I agree that Murdoch is amoral, ruthless and a manipulator, what I was referring to when I characterised him as "stupid" was this tweet, not the fact that he may be intellectually challenged in his business dealings.
To think that this person has so much influence and such a loud voice worries me. Remember, he has the ear of the movers and shakers in the world and to find he has this level of ignorance is deeply concerning. Though, of course, he probably has numerous ulterior motives for shooting his mouth off like this.
As to the point John Bailey raises. My comment was a twist on the saying "If you're so smart why ain't you rich?"
Murdoch the face of the undeserving rich.
