Like any area of the university outside of the hard sciences or engineering, I think it varied. I had easy classes. After the engineering sequence in calculus and physics, introductory astronomy was a breeze and lower level History or literature classes weren't ballbusting. OTOH, upper level classes in 19th century Russian lit (I think we averaged 1000 pages of reading per week), Soviet style economics and Soviet economic geography and History classes taught by my adviser (notorious hard grader) were as challenging as anything I would later take at Chicago.
At the end of the day, liberal arts vs. business is a legitimate debate. I'll, however, never bring myself to agree with the notion that a humanities or social science degree isn't inherently more challenging (particularly if you're in honors and go out of your way to make it challenging) and educating than things like family science or sports management.
