Classes in School

Many times, when teachers start teaching us something new, a student asks them, "When in our life are we going to need to know this?"  Their response? "You probably won't, but we have to teach you it anyway." What's the point of learning material we aren't going to have to know?  In my opinion, school should offer more useful classes that are needed when a person is out on their own.  For example, personal finance.  As a student, I would take a personal finance class if my school offered it.  Some of the information we could learn is: saving money, budgeting, and savings/checking accounts.  Another class they could offer is one which teaches social skills.  A certain thing we could cover in that class is interviewing, or being interviewed.  We could learn about different types of cultures, since we will someday be working with lots of people from around the world.  Also, we would need to be taught how to socialize with people of different ages. I know that some classes already cover this kind of material, but not in full detail.  I think we could learn more about these things, and other subjects as well.  If we had more useful classes, I would gladly sign up for them instead of some of the ones I'm taking now.  An advantage to more useful classes would be that students would be more likely to pay attention and succeed.  I, along with other students, find it hard to pay attention in a class that seems pointless.  If I'm never going to need to know it, why should I be attempting to learn it?  Even adults, mostly parents, always make a comment such as, "What are they teaching these kids in school these days?"  I asked my parents and they agree.  They think it would be more helpful to students to learn things we're going to need to know in the future.
