You know I think I just thought of the script for a new Neill Blomkamp movie...
In a future where the rich have unparalleled access to the worlds greatest intellects, and the poor aren't given the chance to think for themselves.
Seriously, renting minds is the best pretentious social commentary thingy yet!
It seems like it would fall hugely flat logically, as the point of these things tends to be "We are all equal", when in that situation the rich would be leagues above any protagonist, and presumably the viewer, so either the movie would have to portray them as prone to ridiculous mistakes (which would be easily avoidable to an actual person of massive wealth and intelligence) or make the protagonist a rogue one of these (which still has the problem that these people should be so far above us in intelligence as to be wholly inscrutable), or perhaps getting help from one of these ultra-rich people (which defeats the purpose).
I mean, these would be unethical people of massive wealth and unparalleled intellect. They'd steamroll anyone who could even consider stopping them. Given that they could augment themselves in other ways, these would be humans-as-gods powered by a permanently enslaved forsaken underclass (whom they could simply reduce to brains in jars), as robots do what the poor once did. That would be an interesting book or movie, but it'd be pretty bleak.
Or it could be brain-eating, whatever.
