To me, the problem is that we say that learning math and science only makes sense if you want to pursue a career in that area.
The fact is, regardless of your career, knowledge of math and science is critical to your success, even if you are an MBA. In today's economy, with its focus on technology, if you do not have an understanding of math and science, it puts you at a disadvantage, even if you don't go into a career directly as a scientists.
And I think math and science is like serious exercise for the brain. It has to make you smarter.
