I studied marketing (which I don't regret), but that is not an expensive class to teach! You need some books, some computers and a lecturer and a TA. That's about it.
Studying something like Biology or Engineering or Comp Sci where you're actually consuming resources as you learn (be it dissecting frogs or cloud computing or 3d printing equipment), so you'd expect that there's a cost that business, law and arts courses don't really have.
The only consumable resources that I expended in my Comp Sci bachelor's degree was some person-hours of ass-in-seat, fiddling with hardware design software.
Everything else was done with off-the-shelf, typically free software, mostly on my personal laptop. If I didn't have one, I'd have done my homework in any of the general-purpose computer labs, also used by mathematicians, art majors, and medical students.
You don't need to piss away $5,000/term in cloud computing costs to get a good 4-year CS education.
