The replies to this post are amazingly defensive. Did you not get the theme? WHY is the theme. You folks stating your specific case seem to have a "why", and a need to defend yourselves even though you weren't specifically attacked.
Relax, you have done well. You have a good "why". Now consider someone who doesn't have a good "why" and also doesn't have a college degree to at least prove they can complete something. It's not a perfect indicator, but it's an indicator.
