What shouldn't be taught in schools?

People say that it is the responsibility of the schools to teach kids in all areas of life. Schools not only have to teach the three Rs mixed with science and technology but they also need to provide sexual and health education; character education; career guidance; proper diet; and financial planning.

Not to mention all the state and national assessments piled on, teachers and schools are getting bogged down with too much to teach. At what point is it that some of these “classes” can be taught by someone other than school?
