One thing that might be skewing the results- this chart is based on regularly-taxed income, which would exclude gains made from things like stock options and grants. I would hypothesize that a good chunk of CS and Engineering majors have done very well for themselves, but not from earning salary alone. However, age is probably the single biggest factor here. Older people tend to be much wealthier and earn far more, and some "tech" degrees like CS weren't even offered (or offered widely) until relatively recently. I would also posit that the rise of very wealthy engineers is a relatively recent phenomenon, compounding the age issue.
