I get that some portion of the population cares about social status when selecting a degree, but a lot of people do want steady, enjoyable jobs that pays well, regardless of the social status it confers. Doesn't really explain why the percentage of CS majors went down. I do know CS majors went through a huge boom in the 90s and then a shakeout happened after the dot com bust. As for CS majors in Congress, well, I would not expect them to start popping up until another decade or two goes by, given the average age of a Congressperson and the relatively young age of CS as a discipline.
