Which degree to complement a web developer?

What would be the best degree to complement a web developer?

My local uni and cc offers both Computer Science and Management Information Systems; I can't find anything else that would be adequate.

I figured MIS would be best for someone wanting to get into the management/executive field of technology while CS would be best for someone wanting to become a highly-paid Sr Developer. But I've heard of CS majors that hold C-level positions.

What's your thoughts? Any questions for me?
