So, shouldn't the supply and demand principle be applied, and salaries lowered? Sauce for the goose, etc. [edit: Relating this to discussion about teachers' salaries]
Absolutely
I can see where you draw parallels with teachers but unlike teachers cops are willing to move just about anywhere in the country to land a job. The RCMP, for example, send you off where they want you, not where you want to go, and only after many years on the force do you have enough seniority to start inching closer to where you want to be.
I think most people early on in their careers if they are single without children move to land a first good paying job, teachers included. I will admit I don't have stats for any of that, but I had to move early on out of town to land my first good paying job out of university
