Okay, consider this. Tomorrow, or the next day, genetic engineers discover how to make us immortal. Who gets it? Doing it to everyone would result in overcrowding, starvation, probably a resulting general slide into global economic recession, wars for land and resources, and so on. It would screw us and the planet. Only the smartest 1% or 2% of people? Those minds might be able to do the most for humanity. Test people at five year intervals to get a general idea of IQ and reasoning ability, and give it to the highest scorers? Give it to the rich people? After all, they are the ones with the clout to create lasting industrial bases which can take us to the stars. They are the ones feeding half the world (and screwing half the world). Give it to poor, uneducated people for some reason? So, who gets it, and why?
