I hear ya', and BB seems to make it work as well as anyone.
Still, as someone who watches this stuff happen in the business world all the time, I have a problem with it. There should be only one qualification for someone getting hired in any organization: they are the best qualified and best fit that can be found in the general population. Anything less is laziness and/or serving a different agenda than the well being of the organization and all the other people who are invested in it and rely on it.
Once you compromise that standard, it is a slippery slope that easily leads to situations like what we see in the NFL front office, where people are being hired from the Jets and other personal networks, apparently without any effort at a global search to find the best possible candidate. And then rationalization sets in to justify it, and the laziness about hiring sets a precedent for laziness in the organization in general.
I saw this not long ago where a VP in a chemical company hired a nephew to run their Manufacturing Safety operation. The guy was qualified but never would have been the winner of a competitive search process. That VP lost a ton of respect, and created a good deal of resentment in the plant crew, when he used a shared asset (the job) to put forward a personal agenda. And the fact that it was a critical job regarding everyone's safety brought crystal clarity to the situation. Unconsciously, people start to have a "WTF" attitude about things that they previously cared a lot about, because the leadership has lowered the standard in such a visible way. Lowered expectations and standards in one area spills over into others.
I know this won't be popular here, but I don't like that BB hires family. It is the only thing I've seen that he's done that actually "compromises the integrity of the game" in my view.
In family businesses like the Krafts, it is common practice of course to have the inheritance thing going on. And, there's a flourishing business of consultants who work with family businesses helping them work through the extra complexity and limitations of having the accident of genetics be a priority factor in determining awarded responsibility and authority.
