Could be... In my own lifetime I've noticed that we've gone from every little town having it's own independent pharmacist to the near extinction of those guys.
My little town had a pharmacy 30 years ago and the town just up the highway had 3.
Now our town has none, and the town up the highway has a Walgreen's and about another 10 miles up the highway is a Wal-Mart with a pharmacy.
So while the number of different pharmacies has obviously collapsed into just a handful of giant corporations, I'm wondering if the net number of pharmacies has changed much?
