CS programs have high attrition rates because programming or "coding" has been touted as easy money for a couple few decades now. When people find out it's not so easy, they bail. Holding a few layers of abstractions in your head is not something that everyone does easily. Just as keeping most of the structure of a 4-novel-long story in your head is not something everyone can do, hence why being a successful author is not something that everyone can do. Start telling everyone that being a novelist is easy money, though, and you'll see Comp 101 courses filling up and the attrition rate correspondingly go through the roof.
