There exists a system that thinks that teaching the framework of higher order math is a good thing to middle school and high school students.
Simply put Mathematics in a vacuum is simply pushing numbers around and in such system it is never known the point is. This was my problem after finishing up calculus I in HS. The fact that at this point most higher math is created/used in the sciences and what I did in high school had a "purpose" in such systems would have kept me more interested knowing that the spherical harmonics which are trig functions that define molecular orbitals than just doing random trigonometric integration.
I guess I like math either way, whether it is tied directly to the real world (I'm an engineer) or presented purely as an abstraction. This is sort of the dichotomy between Newton and Liebniz (see: Liebniz-Clarke Correspondence--absolute vs. relative space). But, I guess most people prefer to see the connection between the mathematics and the real world. However, sometimes the purely abstract in time becomes applied. For example, until recently, elliptical curves were abstract, with no apparent application. Then, they became important in cryptography.
