<p>One of the reasons nursing school has to limit student number is because in order to teach a nurse must have a Master in Nursing. They cannot have a masters in another related field such as Health Services administration or Public Health which limits the availability of instructors. So the demand may be there but there are not enough resources to teach.</p>
<p>When I was a young nurse, hospitals did not limit new grads as much as today. In fact they had special orientation programs to get new nurses started. Due to cost of care, I imagine the money to support this type of on the job training no longer exists.</p>
