While I may not grasp the full context of nursing vs medicine, when it comes to my healthcare I would expect my doctor to be able to perform the full extent of what my nurse could do, whereas the same could not be said of the reverse. Nursing is a tough job, with demanding hours, but I could get a nursing degree in 2 years, whereas I probably couldn't even get into med school, much less get through 4 years + residency. (I'm a biomedical Engineer, have most of the background). Also, your argument doesn't hold up. If every software developer was worse, it would be as difficult to get into because everyone is worse, not just current devs.
