Re. prescriptions not being profitable enough to justify hiring more pharmacists:
Isn't pharmacy largely considered a loss leader now? As in, patient gets a generic script, goes to Walmart for his $4 drug. Pharmacist sighs and shrugs because he knows Walmart is losing money on the deal .... While the patient is waiting, he notices there is a flat screen TV on sale! And maybe his wife comes along, and while she's waiting she browses in the kids clothing section and gets $75 worth of Mary Kate and Ashley merch. And look, a rollback on a jumbo pack of diapers! And the kid has come along too and sees a $40 toy that s/he just HAS to have ... and while they are shopping there, may as well pick up some toilet paper, dish soap -- and look at those cool new BBQs for sale cheap!!
All of a sudden that $4 generic more than pays for itself, see? But it was the prescription that got them in the door to shell out $$ on other things. So I'm not sure it's as simple as saying that they wouldn't hire more pharmacists based simple on reimbursement rates. They definitely might hire more pharmacists to attract more customers in for "real" shopping while they wait.
