Orwell's fundamental problem was that he didn't understand how organizations function, and how the whole differs from the sum of its parts. He saw only the trees and not the forest. He understood what motivated individuals well, and just extrapolated that out, which led to erroneous thinking.

Aldous Huxley was quite the opposite, which is why his vision of government and society has in many ways materialized but his vision of the individual has not. There was a great post here a couple weeks back about the two that illustrated it.
