No, neither Brave New World or 1984 were prescient in the sense of making an actual prediction of the future, specifically with regard to technology, and its social consequences, which I think is what the original poster was looking for. You're right they are parodies of their own time, even more true now than when written.
Western governments do far worse than put rat cages on enemies of the state, the definition of which can be changed at any time if defined at all.
Neither monogamy nor meaningful sexuality is not encouraged by this culture.
The world of Brave New World was absolutely horrifying. A completely empty, meaningless existence designed and controlled by experts and bureaucrats. A type of existence we increasingly see today, and one that, like the people in the book, that many today seem to be happy with.
I don't believe the character living outside the system was supposed to be seen as superior to it, merely an alternative that would develop.
