Salary should not be much of an issue at all - pharmacists are very well paid, and if you become a doctor just for the money you aren't going to be very happy. Either way you will have a comfortable lifestyle.
Personally, I've been thinking about working in healthcare for years. I have a BA in Psych, but I don't think I would want to be a psychologist or psychiatrist because it is too much responsibility and too many gray areas - you never know how your words might affect a very fragile person. Pharmacy is more straightfoward - if you take these drugs together, you'll get really sick. I worked in a mental health center, and sometimes things felt hopeless and I didn't know if I was really helping people. In pharmacy, it's more straightforward.
I have never wanted to be a doctor because I am squeamish - I can't handle vomit or feces or blood. Also, I want to be able to work part-time if I choose, and never have to work midnights or wear a pager. And again, it's more responsibility - diagnosing is very different from checking for drug interactions, and again it's just not quite as straightforward.
Plus, I really like the patient-pharmacist relationship - in my experience, pharmacists have more time to talk to patients and help them solve problems, and people are really grateful to have pharmacists willing to work with them, and not having to pay for a doctor visit. For example, my dad had a bad accident earlier this year, and asked the pharmacist for help with pain management when our insurance decided to not cover anything related to the accident. The naproxen the pharmacist helped him find manages his pain just as well as the ultracet the doctor prescribed, and he also got a wrist brace, vitamin supplements, etc. And oftentimes patients will see their pharmacists every week, and only see their doctors once a year, so they know us better and trust us more. Our pharmacy manager is a diabetic educator, and I think that's really interesting - he can educate people how to eat better and take care of themselves so they need less medicine.
So, yeah, my personality type really meshes with the type of problem-solving and decision-making a retail pharmacist makes, along with the type of patient interaction.
