I would agree with this, though also add that I believe the rant is largely focused on the business aspects of why people leave their jobs. I understood the absence of this discussion as a concession that there are some decisions made in a business that have little or nothing to do with business, and as such, that business cannot influence as heavily.

Such decisions may indeed be bolstered by business choices (not getting enough pay anyways, no where to go anyways, and so on), but if the impetus is a non-business decision, then it's likely no amount of negotiation or "shielding" will change the outcome.

At least, in my experience, such tactics usually come more as a slap in the face rather than a tempting offer.
