I'd be interested in trying out the following idea: How about we don't mandate mathematics and science courses in high school, and especially in early college? The benefits of this are two-fold. The people who want to pursue other interests are freer to do so. And, more importantly to me as a mathematics graduate student, the people who are interested in math and science can go much much faster, and attain a higher level earlier on. As far as I can tell, most other countries with successful mathematics cultures operate more like this. In my math PhD program, the foreign students almost universally arrived better prepared (more knowledgeable and skilled) than the Americans. I believe the gen-ed requirements and general lack of specialization in American education may have a role in this.
