Winston's world and the movie Gattaca

As I was reading 1984, I remembered a very similar setting in a movie I saw, Gattaca. In Gattaca, there was very closed monitoring of the citizens and a clearly defined class hierarchy. If a crime was committed, in Winston's world, the police would eventually find out because of the telescreens and, more importantly, the Thought Police. In Gattaca, the detective work consisted of scanning the crime scene for any traces of your genetic footprint: hair, nails, skin, etc. In 1984, the government controlled its population by means of cultural conditioning that lasted throughout one's life. In Gattaca, the control would not so much be behaviorally-based techniques, but would start much sooner, in the womb. By using very advanced and precise genetic engineering, the parents could choose the perfect child; no diseases, no brain or muscular damage, perfect health, excellent looks, etc. The control lay not in the hands of the government, but at the mercy of the parents. The parents' perception of what a 'good enough' genetic makeup, and therefore qualities of the unborn child, can easily be influenced by the government.
