Living through the decline in IT, has made me realize, that the question shouldn't be "What happens when the required number of pharmacists decline?" but one of "What happens when technology and law makes having a pharmacist in every corner store a luxury and not a requirement?" This is far more important, because it allows the use of cheaper pharmacists. For example, what happens when stores install tele-pharmacy dispensing? The dispensing is done by PharmTechs, the pharmacist remotely checks the script and counsels the patient through (essentially a) webcam? That means rolling three or four pharmacy stores into a two person crew is very easy to do.
The number of required pharmacists will decrease in our lifetime. And for most of the people on this board, that will impact them, because 30 years will likely be 10 or possibly 20 years from retirement in 2036. This means that pharmacists that serve highly specialized roles or those that serve multiple areas will be kept and Joe (or Jane) Doe, that only counts, counsels and takes cash is SOL.
High senority (or rather high salary) will be the first to be RIF'd (Reduction in Force) or my favorite Reduction En Masse (REM), unless they fit into minority status. The number of part timers will increase, because the cost of two part time pharmacists with no benefits is better then one pharmacist with full benefits. This means pharmacists who are in it to stay at home are primed to get spots, those that want to work full time, better find multiple stores or hone teaching skills.
In short, learn as much now and keep abreast on as many skills as possible. Branch out to all areas of pharmacy or work at becoming the top 2 or 3 in a particular area.
It's also interesting that the spending of capital on R&D can be attributed to several key factors. Of note, a number of bills passed in the 90s that made R&D more profitable in terms of tax reduction or tax credit. In essence, business lobbied to make it more profitable to spend money in R&D across a wide range of fields. Ultimately there is some benefit to society, but not nearly as much as to 'the man'. Another valuable note is that money has largely deflated in the last 10 years. Ten years ago, I made around 40k a year, last year my AGI was around 88k. That's more then doubled my taxable income, however my buying power only raised about 10% and while that doesn't include funds going to retirement, it's still a poor ROI for 10 years of service, training and growth.
