Aldous Huxley

"The society described in 1984 is a society controlled almost exclusively by punishment and the fear of punishment.
In the imaginary world of my own fable, punishment is infrequent and generally mild. The nearly perfect control exercised by the government is achieved by systematic reinforcement of desirable behavior, by many kinds of nearly non-violent manipulation, both physical and psychological, and by genetic standardization.
Babies in bottles and the centralized control of reproduction are not perhaps impossible; but it is quite clear that for a long time to come we shall remain a viviparous species breeding at random.
For practical purposes genetic standardization may be ruled out. Societies will continue to be controlled post-natally -- by punishment, as in the past, and to an ever increasing extent by the more effective methods of reward and scientific manipulation."

If you can achieve mind manipulation you won´t need punishment, since people will do EXACTLY what they are supposed to do.
This I do not think is impossible, I guess technology and its important branch psychology, can provide all means, but the question is:
What is it that people are supposed to do or how are they supposed to behave and, more important, WHO says what?

I am not a fan of nature, I do not believe that ALL what nature does is good and is the best.
We need to reproduce ourselves in order to go on for doing whatever we are supposed to do in this earth.
We do not know why we are here or how we came here, we do not know who we are or why we are.
We know that we live a certain amount of years, that we will die, that we have to leave a part of ourselves to go on with the job begun millions of years ago.
To assure the continuation of a species which is endangered to survive, you have usually to "overdo".
A tree spreads millions seeds, but just a few become a new tree.
Humanity has reached a good point, in which most of the seeds survive, so the answer should be only one: plant less seeds.
When you have a reduced piece of land you plant just what is more likely to grow.

I am not a Eugenist, but I understand.
Still the big question: Does somebody have the right to decide?
