Yes, nursing is like other careers in that there is a hierarchy of jobs (and salaries) based on scope of responsibility, education required, market factors, etc. While there are a few exceptions, nursing positions that involve taking more responsibility, require more education, and involve doing less pleasant and/or less popular work pay more than positions that are popular, involve working a popular schedule, require less education, and involve a more limited scope of practice (i.e. being responsible for the care of only a few patients vs being responsible for managing or teaching those who who take care of many patients).
What many people who switch careers in nursing fail to appreciate ahead of time is the time and effort required to move up the ladder. An advanced education alone is usually not enough. As a practice discipline, most higher level (and better paying) positions are given to people who have both a strong educational foundation and also sufficient clinical experience to develop expertise.
Here's an extreme example to illustrate the point: A person who wants to be the Director of Nursing for a large organization can't just get a Master's Degree in Nursing Administration and get the job as a new grad. She would need to first get a nursing degree and practice as a nurse for a while to establish her basic competence as a nurse. Then she would be eligible for promotion to a lower-level or mid-level management position. After working at that level of management for a couple of years, she would be eligible for promotion further up the ladder. She would need to earn her MSN somewhere along the way (though there are some entry-level MSN programs). It would take a period of several years of both education and work experience to qualify for such a high-level job.
While each specific career path is different, the general principles usually hold true. One moves up the career ladder by getting the needed education and/or certifications and also establishing expertise through practice at lower levels of the career ladder.
Salaries vary greatly based on the region of the country, cost of living, etc. But generally, the upper levels of nurse administrators, educators, and advanced clinical practice nurses make about 1.5 to 2.0 times what the starting salary is for new RN's in entry level positions. A few people at the very top make a little more.
