Taking more math in school will raise your income

No causation required.

As the submitted article here notes,

"Of course, finding qualified teachers to teach advanced maths courses will not be easy."

Not easy by far. Here is a detailed article about just how difficult it is to find elementary school teachers who know even very basic math

http://www.ams.org/notices/200502/fea-kenschaft.pdf

and how especially lacking such teachers are in school districts with mostly poor students from ethnic minorities. One finding from that article illustrates the grave nature of the problem:

"in my first visit in 1986 to a K-6 elementary school, I discovered that not a single teacher knew how to find the area of a rectangle."

I once lost out on a job because of my Calculus grade in college.

This finds me balking from math heavy software development jobs because I feel like my math skills will hold me back(or at least slow me down). This is sad, because many of the most lucrative software development jobs I see are generally pretty math heavy. I would venture to guess this is the same in other fields as well.

Won't his face be red!

correlation mistaken for causation...so frustratingly pervasive in our society.

I even implemented the thinking style I picked up in Analysis, such as the notion of a compact space [as it relates to social cohesion], while writing a paper on Aristotle's Politics in my sophomore year. I didn't use any math words at all, and instead drew a diagram to illustrate what I meant, and really enhanced my argument.

Anyway, bottom line: I took a shitload of math to make myself smarter and to enhance my nerd cred; nobody seems to care; maybe someone here will give a care; since I'm ultimately probably going to be self-employed anyway, perhaps my improved mental acumen will pay off financially, but as of yet it's unclear.
