The world needs as many highly educated people as possible. The problem becomes when you make higher education a business and attach publication as a requirement for advancement. Then you are diluting the quality of research in pursuit of a “high volume” model. In this model people don’t follow passion they follow the path of least resistance and we all suffer for it.

I would also ask yourself how often and how long you work compared to this doctor. I think standard for nurses is 3-4 shifts per week. Doctors work much more than this and often have out of work responsibilities as well. The hourly rate is much closer than you make it out to be.
