That is one of the two things really keeping me on the fence, there are a decent amount of articles from credible sources predicting saturation and serious employment opportunities in 4 years.
Have you spent time watching the market in the area you are wanting to stay in? You need to look at how many pharmacy schools are near there and how many pharmacy jobs are even posted for that area or within a distance you would be willing to travel to work. If the area is growing, there may be an increase in retail jobs, but likely this will only occur if the area is growing very rapidly and is not already covered with pharmacies. Next consider who those jobs are with, RiteAid has been closing stores, so there is already concern there that those pharmacies may not even exist in 4 years. The other chains have numerous posts on here from people who work with them and are very unfavorable (note that this is not people upset with pharmacy, but with the company that is putting excess tasks/expectations on the pharmacist). I would watch these jobs while you decide what to do, then you need to consider what you saw, as that will only be worse in 4 years. Another consideration is if you will be able to work in the area you desire as an intern while in school. This could help you to get an initial job if you can network with people in the area, but, if you are having to move away for school, you may find that getting a job in the area you desire is nearly impossible.
