I wish I was a business major instead of chemistry. Can you explain why wages won't drop? Everyone says the same thing, but no one gives a reason. I believe you, but whats the reason? (And I don't remember anything from Econ 101 that I took 6 years ago. My apologizes...)
The entire wage of a profession simply cannot drop over night. The are too many people with too many variables who will fight to keep the wage they earn. People become fixated on x number of dollars per hour or per year. They will do whatever it takes to maintain that.
How businesses get around that is either by firing people, not hiring more or cutting hours.
Think about it, the economy is in a funk now correct? But businesses aren't cutting wages of their employees are they? Of course there are some that have been shifted to a lower paying job, but the job they had didn't lose its previous pay. They were just shifted to a different job. Instead they save money by cutting peoples, hours, etc etc. If you start cutting wage amounts across the nation you'll have nothing short of a riot on your hands.
Instead wages may not experience much growth once the shortage is gone. You might make say 120k a year for five years. After five years, maybe that 120k is really worth 105k if you consider the effect of inflation. The thing is, that is still a good chunk of change and nothing to sneeze at.
Seeing as this is a professional program (compared to, for instance, graphic designers or school teachers who usually who are not professionals) you will not see the wages dip below a certain amount. We can reasonably assume that we are all intelligent individuals in the industry and can tell when we're being screwed. Because of this facet, they simply will not stand for a stagnant wage for too long.
That being said, those of you who say the wage will decrease are ignoring a very vital part of the profession. We are in the midst of a revolution in the roll of pharmacists. No longer are pharmacists the quiet guys who sit behind the counter and count by five. Today pharmacists are a very integral part of the treatment of a patient.
Pharmacists haven't even reached the maximum amount of patient benefit they can give. MTMs, for instance, are effectively in their infancy yet will have the ability revolutionize the medication therapy of patients. In ten years time I would bet it becomes a staple of many pharmacies.
Then there is the fact that it is not too far fetched to start seeing pharmacists working hand in hand with docs in a hospital on a regular basis. Docs would diagnosis while the pharmacist would help with drug therapy. As drugs progress to more protein based in nature (which is still about 15-20 years off or so) MDs will be even less aware of their arsenal of medications.
In essence, the knowledge and functions of a pharmacist are going to increase in the coming years. That alone will keep wages from dropping. Everyone just looks at the hard numbers of people entering the profession without looking at the big picture. Sure you won't be seeing 50k sign on bonuses anymore, but those were ridiculous to begin with.
What I think you will start seeing, within the next decade or so, are pharmacists becoming specialized in much the same way MDs do. Granted, that exists to a certain extent today, but I believe the training will mirror MDs training more than what is done today.
I realize this a very long ramble, but hopefully it provides some insight into the situation.
