Because for those other subjects it's often correct, so it would be to knock in an open door.

Math has a much stronger claim to be generically useful. Related fields, such as physics may in fact be seen something worth studing more because it teaches you how to apply math, than for the likelihood that you may end up in a job that requires the physics itself.

My own experience is that math/stats is by far the most useful (non language) topic I studied in school/university, even more so that Computer Science (and I work in IT).
