Human rights are relative, not absolute. What we consider 'rights' have been considered 'privileges' by damned near every society since the birth of civilisation. We live in a time of remarkable peace and prosperity, utterly unknown to the tens-of-thousands of generations that came before us.
That aside, presuming society does not collapse in the next 15 years, genetic manipulation is only a matter of time. Whether you choose to call that eugenics-by-default is your prerogative. Selective breeding would be particularly difficult to enforce upon humanity. The desire to procreate is the driving force of all life, and you can't just say 'sorry, not you' without creating a brutally restrictive society - a society so restrictive that I'd venture to say it would stifle the 'Super Men' born of these eugenics experiments, whatever the superiority of their genes. For hundreds of thousands of years, there have been countless da Vincis, Archimedes', Beethovens, and Einsteins; the simple fact is that these potential geniuses have been crushed into obscurity by a) repressive societies discouraging progress b)Death due to disease or conflict c) lack of education.
The birth of a genius is not that uncommon - if you looked at the average IQ of the Escapists here I'm sure you'd see an upper-end skew - however, I am likewise certain that none of us are going to be da Vinci, Beethoven, or Archimedes, due to the complex play of society and development that gives someone the motivation and the 'divine spark' to USE their full potential.
Consider the population of the world at present - we should be DROWNING in astounding genius if it was purely based on genetics. It ain't. And hence, we ain't. Your genes are important, but your upbringing is what truly makes you. There is no gene for 'enlightened'.
EDIT: A simple example. Ask yourself this question: Are those more successful in society than me genetically superior? Do you think Bill Gates is a bundle of superman genes, passed down by fate to make him better than the rest of us? Or howsabout George Bush (*snort*)? Is he of better stock? Genetically superior? Hell no, I'm sure most of the people here are of just as good breeding as that moron - and if not, better breeding. You can see clearly now that genetics has piss all to do with success in today's society.
Now, if we lived in a post-apocalyptic wasteland a la Fallout 3 --> this is where your genes will count. For example - I'm a nut job survivalist, rugged yet educated. However, if the shit really did hit the fan, I'm an evolutionary dead-end. I'm short sighted. Game over. Some dip shit moron with a club foot, diabetes and a congenital heart defect - who has good eyesight - could out-survive me quite easily once I lose my glasses.
