There is no reason for always requiring new editions of books and paying incredible high prices for these books. Why are professional education books like computers books at around $20-$60 with lower sale numbers while college books above $80/$100 a piece ?
A lot of people a getting lot of $ in their pocket in this mafia system.
Give incentive to schools/college/etc and teachers when they use cheaper books and potentially establish a committee to review why these books are so expensive. The books should be mainly created by full time education system employees, and not exclusively by external contributors.
