Oregon State Basketball, UCLA basketball, innumerable fathers givin assistants jobs on colleges brings a son with them.    

I worked for a company that pretty much encouraged nepotism with not a whole lot of problem.   The feeling was that family in the same company built loyalty and bonds of family/friends.    Most was fine, but there were some pretty egregious mistakes as well.    But, not sure it was any worse than companies that reward people for other bias.    It was a small town, hard for a lot of the workforce NOT to be related in some way or another.  LOL
