i'm sure it's happened somewhere...I'm not sure but from what I've seen, incredibly hard to game recruitment. Even if you do, the kid won't survive long -- it's up or out every ~2 years.

Seems like a lot of work for not much payoff.

What is encouraged is treating everyone leaving whether regrettable/non-regrettable with a great deal of love and care -- placement services are pretty good. There is a good chance those ex-McK folk are future clients.
