Because while you're getting the benefit, you're not the only one benefiting. The benefit applies to you as well as to everyone else. So your calculation should be "I paid $58,440 in taxes, but I saved $32,000 on tuition for myself, so I actually only paid $26,440 to help everyone else in the country get the same $32,000 education that I did."

Why do you live in a society, where you depend on other people, if you're not willing to help those who depend on you?
