Unlike literature, history, politics and music, math has little relevance to everyday life. That courses such as "Quantitative Reasoning" improve critical thinking is an unsubstantiated myth. All the mathematics one needs in real life can be learned in early years without much fuss. Most adults have no contact with math at work, nor do they curl up with an algebra book for relaxation.
I think we do need some math. It is the third best substitute for real-life problem-solving exercises. Physics is the second, but to do physics you need to know math, otherwise you'll end up waving hands for an hour, trying to understand or explain how the world works, when 30 seconds and a simple formula would suffice.
