Wages they think they deserve. There's always two sides to a story.
Let's then change things so that management wages are decided by the people working under them. That would create _huge_ savings for companies.

This is most interesting, because it flies completely in the face of my experience. I work in the UK, and am head of department at a private school. There have been many times when I might wish to have bypassed the normal recruitment process, because there was someone I knew who was perfect for the job. I've always been given to understand though that in the UK at least, headhunting of this sort, poaching talent, was illegal (although I can't easily find evidence of this!). Indeed, even contacting someone and inviting them to apply through the official channels is frowned upon (as it sets up potentially false expectations).
A very quick Google would suggest that the sort of poaching we're talking about here is certainly illegal in some parts of the States (http://www.linkedin.com/groups/Job-Poaching-is-unethical-illegal-156213.S.238357511?_mSplash=1) so it's odd that it's being encouraged to this extent on a more federal level.
You are talking about hiring one person and not allowing anyone else a chance to get the job. Not good. This here is about hiring from one set of persons and not allowing anyone in another set (employees of certain other companies) a chance to get the job. Also not good. It's about fairness towards all possible employees. Whether you exclude anyone except your favorite candidate, or just anyone from school B, C and D when you work at A, that's about the same thing.
