One of the craziest things on earth is that books are becoming more expensive everyday when there are so many poor people around the world. It is crazy because poor people who love books cannot afford them, rich people who can afford would rather spend money on luxuries but books and book sellers would be disappointed for neither the poor nor the rich is buying books. Then, who is going to benefit from this weird situation?
Anyhow, knowledge is priceless. May someday we don't have to worry about how much to pay for books.
