One reason it takes so long to graduate is that schools are designing their degree programs so as to maximize the length of time they can hang on to a student and squeeze tuition, fees, room and board etc. from them. This doesn’t have to be.

The other reason that people are taking longer to graduate is because the awful economy is requiring more and more students to work while attending classes, and that’s almost certain to lengthen the stay. (I teach at a two-year school where at least 80% of our students work.)

But yes, the other reason is as you stated–too many multi-kulti, Indoctrination 101 classes have been added to everyone’s degree plan.
