Since the 70s, the percentage of students with bachelor's degrees in the humanities has not increased. It's always been around 16-17% of total degrees earned.
Social science has been dropping as a percentage of students with earned degrees in those fields, but not by much.
Math and science has always hovered around 8% of total degrees earned.
Computer science (amazingly) has not grown as a percentage of total degrees earned since the 70s.
Business majors haven't grown as a percentage since the 80s.
Education majors have fallen dramatically each decade, taken up primarily by other fields.

And yet, here we are across the board, with low wages (comparatively to previous generations, comparatively to older workers, comparatively in almost every way measurable), massively increasing education costs and a really, really poor job outlook for young workers.
It's a canard, plain and simple.
