Instead of focusing on Maths why don't we completely re-think High School? For starters let's get off this idea that everyone should be preparing to go to college. Sure, have a college prep curriculum for the 20% of your students who are going to go to college. Everyone else would benefit from vocational training with a solid educational foundation - that way should they decide to go to college they still could, they just may not be able to get into the most competitive universities.

For those going the vocational training path you'd want to have a program where students in their 1st and 2nd years are spent sampling a variety of trades and vocations so they can determine where they want to focus for their 3rd and 4th years. Let's face it - even computer programming can be taught in this manner and people would be able to graduate from High School and get a job programming.
