You're looking at the competition from the wrong side. We don't want there to be a ton of competition between practitioners, we want competition between employers. This is basic economics here, when supply is greater than demand, the price goes down (and so does your bottom line).
Nobody is discouraging anyone here, were talking numbers, and they don't lie. Sure these are projected for job creation but even with a margin of error of 10%, were still way over. If its your soul desire to become an NP, become an NP, nobody is stopping anyone. We're merely looking at the numbers and saying, yeah, not looking great. Also, you cannot compare NP education to medical school, pretty sure this is obvious here. The screening for medical school is harsh and is so for a reason.
