I think there's a point where further mathematical prowess no longer holds any sort of competitive advantage for the average person. That point is probably grade 6.
The average person will do just fine in their lives without needing to factorize a quadratic equation. They will do swimmingly without knowing the relation between ln and e. The average person will, after high school, never again have to utter the word "pi" in a non desert-related setting. Similarly, "'x' equals" will become nought but a forgotten dream.
Modern life makes no mathematical demands of 98% of humanity. The only mathematical skill beyond basic arithmetic that most people need to know is compound interest, and most people don't know that.
Knowledge is driven by need, and there's simply no need for most people to be anything but marginally proficient in math.
