My high school English taught writing form, paragraph structure, how to present and defend a position. You can't make a sale with "Well, that's not right, this is, 'cause it is."
History was another. I hated history, never saw the point, but out in the real world, deciding who to vote for, figuring how to buy a house, why gas costs so much, knowing the history helps to know the reasons for things. For example, many of our Middle-Eastern troubles stem from the fact that we've spent decades choosing up sides over there and interfering (sorry, advising, presenting, assisting) with their governments in the name of foreign policy and national security.
If you can't spell, form a complete sentence, figure change without your fingers, then you're not going very far in life.
