Where did these employees come from? If they just got transferred from another location, those new openings had to be filled. Also, I don't know the exact percentage, but I know quite a few of the new retail stores were new to the state.
Bringing new stores, with new services, to the SLC area would probably increase the number of jobs.
Employees transferring from suburban locations would not, sincethose employees would not be replaced, due to loss of traffic when business goes to the new center.
This may being in new jobs. It also could follow the path of the St. Louis Centre. I have no idea, and so remain skeptical.
