I think this is a pretty simple and incorrect model. Job desirability is considered based on many traits (salary being one, but far from the only one), with different individuals weighing those traits at different levels of importance. If salary is the most important factor for a job, CE will basically never compete given the talent requirements; if autonomy or impact is the most important trait, it will compete even at very low levels of salary.
