Okay, I'm finally doing some work on this one. 

Since it's near-future, I'm doing a little wiki-research on where we are in genetic engineering technologies. From there I'm going to make an estimate of how long it will be until this becomes common technology, and then add another seventy or so years before we get into the whole Gattaca-like caste system.

I'm trying to make it clear from the beginning that I dont think human genetic engineering is a bad thing, but that it's the way people chose to use it that has turned it into a fucked up system. I'm hoping to write this as more of a criticism of any kind of caste system that denies anyone upward mobility, and a criticism of bullying and abuse in general.
