Huxley was probably the head honcho of MKUltra. Even though BNW is much younger than MKUltra i'd still take his writing with a grain of salt.
Also, Orwell was apparently disillusioned with the
Fabian society and tried to expose them thus
naming the book 1984, the 100th birthday of the
fabian society.
The fabians advocated gradual, stealthy, non-violent
and reformist means, such as state intervention and
control over the conditions of labour, to create a
new world based on socialism.
Huxley on 1984
The first hints of a philosophy of the ultimate
revolution — the revolution which lies beyond politics
and economics, and which aims at total subversion
of the individual's psychology and physiology — are
to be found in the Marquis de Sade, who regarded
himself as the continuator, the consummator, of
Robespierre and Babeuf.
My own belief is that the ruling oligarchy will find less
arduous and wasteful ways of governing and of
satisfying its lust for power, and these ways will
resemble those which I described in Brave New
World.
