Your grandson goes off and forms Green Aircraft. He sells it. More than twenty years later some guy using Google claims that Green Aircraft is related to the company you founded much earlier. C'mon.
And since Green Appliance happens to make aircraft components, guess who's going to be one of my preferred vendors...
Yep, that's right! Try to keep it "all in the family".... one hand washes the other...
And after twenty years or so, the relationship becomes deeply rooted in the corporate culture, whether I remain at the helm or not.
All the peon salesman/buyers/engineers have been thoroughly indoctrinated in the relationship.
Oh, it may eventually fade with time, but generally the more senior employees will continue to train the newbies before they retire. It's called "networking". Probably still going on at Maytag Appliance and Maytag Aircraft. Perhaps not as much as in "the good old days" but I bet it's still there. It's kind of like dandelions... once established, it's darn near impossible to get rid of!!!
