Yep, you're on to us. We wanted to keep it a total secret etched in the tablets of our elk lodges, but we totally prefer the fat, anti-social, greasy fingered, soda sipping dweeb mold rather than simply trying to look for the most qualified individual for the job. It's completely overt - we are even willing to give up our capitalistic ideals and endure dents in our bottom line to maintain this fraternal tradition.
It's probably okay that you know this now though - we are not frightened of loosing our stronghold. We know that you are incapable of taking overt action because we have evidence that is equally as strong as what you have presented, that you are all spending your time having topless pillow-fights in your sororities.
This all makes total sense if you don't think about it and just assume that a significant majority of people in high places are just filled with hate to the point where they are willing to sacrifice financial and technological gains to consciously perpetuate an arbitrary standard.
