It's really not all that good, because you aren't thinking in terms of careers. A (real) engineer goes to school to be an engineer, gets his license to practice engineering, and from then on is largely assured to receive increasing salaries from that point onward. Sure, the tools may change, but real world experience on actual engineering problems is seen as irreplaceable by employers. A developer by contrast is judged by the tools he uses just as much as his tenure, and his tenure becomes a net negative after a period of time. Because wages rise faster and stagnate faster, corporate types see them as replaceable sooner. This might not mean much to people who hop from job to job every year or two, but for a lot of people, they just want a place to work and feel secure. I know a hell of a lot more 80 year old lawyers, accountants, doctors, and engineers than I do 50 year old developers.
