I agree with you that math is pretty much useless in most people's lives. However I disagree that teaching it to everyone is useless. The whole point of making kids learn a whole bunch of different things is that it gives them a chance to figure out if they are, in fact, interested. If you don't provide lots of different topics of learning to children in school, where are they going to find out that one of those topics might be just the thing that fascinates them? Most parents aren't going to expose their kids to every topic under the sun. I think it's great that schools expose kids to math, physics, chemistry, biology, languages, music, physical education, social studies, history, geography, cooking, sewing, painting, carpentry, religion, you name it. I hated doing at least half of those things when I was in school, but I still appreciate in retrospect that I did it, because now I know much better what I like and don't like.
