For many reasons, beginning with forces outside their control (publishers pay as little as humanly possible; lots of would-be writers willing to work for pennies, keeping the pay rates low) and working up to forces entirely within their control (writers playing with their XBox 360s instead of writing; willingness to be to paid stupid low rates for their work).
