I suspect a big cause of nonlinear productivity effects like this is the experience and skills required to do the job. In the example cited, sales, the best salespeople have long-built networks of personal connections. That allows them to bring in deals that new people can’t access. It’s very different than retail work where it’s hard to greatly outperform your peers and little training is needed. So agree models like this can be created but my feeling is the key aspects of the model relate to experience (related to your cash cow) rather than scale. At least for creative jobs.
