I don't know if I'd call the textbook publishers parasites. Books with small audiences are more expensive to print. Isn't a parasite something that takes resources against the host's will while providing nothing in return? How is that true here? As with music, authors that appeal to large numbers of people have the most leverage. When distribution is very costly per copy, the take home for the producer will be reduced. Distribution is a real activity that needs to be performed. There's nothing parasitic about it.
