What's special about the book? It's the cost, proof of work if you will. If costs nothing to write or read an internet post, so bots, cheap workforce and gullible people can be employed. Only selected few buy books, because it costs money, so it's their vote that counts for the author, the publishers and for fellow readers.

I doubt money is the limiting factor for book uptake in the West, particularly in towns with a library. You're instead selecting for curiosity, intelligence and attention span. (Say this as someone without enough of the last.)
