What? I'm not sure where you pulled this concept of that English vs computer science were in anyway comparable in terms of overall pay even in the early 2000s but you might want to cite your sources.
I went to school in 2001 and computer science was one of the hottest fields around by that time, significantly more so than a BA in English. The Georgia institute of technology (Gatech), my alma mater, had a highly competitive computer science career path.
In fact the general advice was that if you really wanted to major in English that it was better to pursue a degree in an adjacent field such as communications so you could more easily transition into journalism, etc.
STEM (doctors, scientists, engineers, etc.) has almost always been a safer career path than liberal arts, assuming you're cut out for it.
