I have no idea why we consider them the same in America, but in most places, even though UIUC is a fantastic technical school, a degree in something called "Enterprise Systems Engineering" should not be considered a university degree. You simply didn't have that experience. And, yes, I'm sure it was horrible.
In my Anthro and other liberal arts classes, my homework was to read a famous literary work, study a movement, a people, a culture or an event and then be prepared to discuss it critically with my peers, often in classes with 5-8 students.
PS -- I need to add that there are definitely students of engineering who treat the curriculum as the science and discipline and art that it is. These students relish understanding the provenance of the discipline and the state of the art and spend all their time in it trying to master the art. It's just more obvious how to do that in the liberal arts because they groom you to do that. I think you have to be more self-aware and self-motivated in the engineering side of things.
