This has always been the weird thing for me. I'm ex-facebook so when I get hired companies will often say "wow you know a bunch of facebook people, lets hire them" not realizing they are both insanely expensive and insanely in demand.

I've always said, why not instead of hiring engineers who work at Facebook or Google, maybe beat them at their own game and instead go for the same crop of people they are hiring? Brilliant college kids who are excited to work for you and can learn from your team and develop into the great engineer you want.
