Degrees are a lagging indicator. The people who graduated in 2004 started their studies near the peak of the dot-com boom. The trough that followed went below the peak in the mid-80s, meaning that people thought CS less relevant in the mid-2000s than in the early 80s. And the ambitious STEM graduates (not business/finance graduates) went to finance, because that's where the good jobs were.
