A lot of the comments make this mistake, but the article clearly talks about both. It snarkily says the Ivy League graduates end up doing strategy and everyone else ends up doing software implementations.
I draw a parallel with some Asian cultures where being tanned is a sign that you're working in the field, so it's better to avoid the sun and stay as white as can be. When I was at accenture, there was a huge culture to "leave code" as soon as you could. Code is for people who do. Mere grunts. You gotta be a decider, a boss. The only career path (I think that's not true anymore) was management track. They even had a subsidiary called accenture technology services to recruit from universities with less reputation, but "keep the blood pure". It does make sense when you're in it, but golly am I happy I left that world.
