If you've seen the news, Korean physicians are walking off the job and striking due to the Korean government's plan to increase the number of medical school slots by 2,000 annually, from 3,000 to 5,000. They are worried about saturation, lower quality, and of course, competition lowering their prestige and salary.
Meanwhile, NP schools seem to open up as easily and often as fast food joints, and many with comparable quality. Why won't NPs demand better of their boards and accrediting agencies, holding some of these for-profit diploma mills responsible and having them cap their class size and stop churning out low quality NPs that saturate the field? The saturation is clear, in my home state of California many of my RN colleagues who have gone back to school for an NP degree are still working as RNs as they make more money at the bedside.
