The Economics of books.
College is full of lots and lots of costs. Apartment, class, food, gas, and BOOKS! A single book can cost more than 100 dollars. But why so high? Well lets think about this. Did you know that book company's will actually send professors free books in the hope that the professor will like it and they can sell the book to all his students that HAVE to buy it regardless of price? The last thing the professor looks at is the how much it costs, I mean he's getting it for free so who cares. What he's looking for are some of his favorite subjects (the things he really likes to teach). So what do the book makers do? They fill the book with 20 chapters (much more than any class could cover in a semester) so that no matter what the professors "favorite" topics are they will almost certainly be covered. And along with a large book comes large cost. So because the book makers understand that all they have to do is impress the professor we get these big books with huge prictags. So all you professors out there, choose a small, cheap book and do us all a favor.
