<p>A lot of colleges in my area are having difficulties filling positions in the nursing departments. One very large state university is currently not accepting new nursing students indefinitely because they do not have enough staff to fill their curriculum. I guess if you’re doing an advanced degree in nursing, a nurse practitioner or physician’s assistant earn as much, if not more than a professor of nursing, and require less schooling than a PhD (although nurses with masters degrees can teach as well, but again, will likely earn more working in the field).</p>
