Good Parenting?

In Saginaw,Micigan lived a rich timber baron named Wellington R. Burt who died in 1919. He was valued to be one of the richest men at the time with a multimillion dollar fortune currently valued at 100 million. You would think his prosperity would be well off after his death with that kind of fortune. That is not quite the case. Wellington made an usual will which is just taking effect this month over 80 years later which passes on his fortune 21 years after his last grandchild's death. That pretty much means his son's and grandchildren didn't any of this fortune to themselves. He reportedly gave his favorite son $30,000 while leaving everyone else with nearly squat. I'm not too sure if this is a good parenting technique or not. It kind of seems like he is trying to make sure that his kids and grand kids don't grow spoiled, however I would take it the wrong way and assume my grandpa didn't like me if I was one of the grand kids. Is generation-skipping trusts a common thing? What implications can this kind of behavior have on one's own children and their grandchildren? Wellington's great great great great granchild, Christina Cameron, is currently set to receive the largest amount of the inheritance at over 3 million dollars. The rest will be split up between three great grandchildren, seven great great grandchildren, and Christina. Is this messed up or what?
