Here is a depressing look at textbook publishing from the Kitchen Table Math blog:

At one time, a writer in this industry could write a book and receive roughly 6% royalties on sales. The salesperson who sold the product, however, earned (and still does) a commission upwards of 17% on the same product. This sort of pay structure never made sense to me; without the product, there’d be nothing to sell, after all. But this disparity serves to illustrate the thinking that has been entrenched industry-wide for decades—that sales and marketing is more valuable than product.

Now, the balance between the budgets for marketing and product development is growing farther and farther apart, and exponentially so. Today, royalties are a thing of the past for most writers and work-for-hire is the norm. Sales staffs still receive their high commissions, but with today’s outsourcing, writers and editors are consistently offered less than 20% of what they used to make. As a result, the number of qualified writers and editors is diminishing, and those being contracted by developers and publishers often don’t have the necessary skills or experience to produce a text worthy of the publisher’s marketing claims.
