The field of pharmacy is growing and evolving. It wasn't too long ago that a doctor would scoff at a pharmacist for pointing out an error or making a suggestion, but now they, along with other health care providers, are relying on pharmacists more and more as THE drug experts. You can get a wide variety of experiences and there is a lot you can do with a pharmD. Just from working in several different retail locations (most of which were within the same retail chain) as a technician, I can say that where you work can really make or break the deal. It can be boring or stressful, or it can be fun and rewarding. As for clinical, which is where I'd like to end up when I graduate, I've only heard good things, especially when compared to retail.
A lot of people compare retail and clinical, but there are so many more options. There's managed care, nuclear, consultant, industrial, home care, the list goes on and on. We had a speaker who ended up as some sort of DEA agent. If you're really serious about it, I'd try to find a temporary part time job, shadow a pharmacist, or anything else just to get a feel for whether you'd like it or not. Schooling is a tough 6 years though. Lots of chemistry and biology, but only Calc 1 is required (at least where I go).
While pay and other benefits should factor into any decision like this, if those are your main reasons for doing it, I believe you would do well to reconsider.
