Yes they do. And, I have a good friend who started at Walgreens about 10-11 years ago. He was a "relief pitcher" in Milwaukee, which meant he worked odd hours covering any shift that needed covering. He might work over night, followed by a late morning/early afternoon start. He also didn't make close to 100K, though it was some time ago. I'm not sure he makes that (or more) now, though I would guess that is in the ballpark. Chicago may have more demand than supply, but that certainly isn't a universal Walgreens starting salary.
He certainly had to have more schooling (read: costs and time) than an appraiser needs, even under the 2008 rules.
