Many adults don't interact with parents on a daily basis; that doesn't mean that our parents would then think it is fine just to disappear and never talk to us again--no birthday, no Christmas, no support if the person was sick, nothing. No one in their right mind would think that faking a death or disappearing was a good way to maximize a child's inheritance, at the expense of the whole relationship between parent and child. None of us have any real notion of how close RG and his daughter were, but there are indications that he was a hands-on parent, even at a distance, given that his staff was told to always put her through when she called.
I frankly doubt if you can be a "hands on parent" when you are 2000 miles away.
Ah, let's be clear; RFG did
not "fake his death." If he had wished to, he could have left a suicide note and walked away.
What bothers me about your argument is that I don't see how we can dismiss the moral and emotional elements of the walkaway hypothesis.
Well, first of all, RFG was a lawyer, and a good one. He looking at the world for a third of century legalistically, just by the nature of what he did. So now we have some factors.
1. RFG has a daughter, but she is out of the area and an independent adult. He does not have to look out for her.
2. RFG, legalistically, sees that, if he retires and gets hit by a bus in 2006, his daughter will not inherit as much. If he dies in 2005, she will get more.
3. RFG, knows that his daughter will, eventually, have to testify that she has not heard from him. Legalistically, he knows that if he tells her, she either can't declare him dead or commits perjury. The simplest solution is not telling her.
RFG obviously does not have to be there physically for LG; he hasn't been there in her day to day life for years. His absence does not change that.
He can contribute greater assets to her, by
not being there. He knows that in 2006, by not being there, LG will not get the greater assets.
If he did walk away, he knows that by not telling LG, he protects her from committing perjury.
We know that 1 and 2 are there; those are the effects, but don't know the intent. On 3, I can very easily see any moderately good father saying, "I don't want my daughter convicted of a felony and ending up in a cell with Large Marge."
It's not that I don't like the walkaway hypothesis; it's that it doesn't fit with known facts, including the fact that he could have retired and walked away with all of his money and done what most people do--leave what's left to his child after he passed away.
Well, because, this way, she'd get more.

One published account was that RFG pension was worth more than $300 K. Had he died, or vanished, after retirement, it would have been less.
The emotional/moral argument really is flimsy.
