I suspect most of those who are against inheritances are people who haven't inherited much or have inherited so much that it was more of a burden than a pleasure.
My dad gave me some real estate before he died. Ok, technically I didn't even inherit it, but the net effect for me was the same and thanks to it I will soon retire early. ERE didn't get me there, but ERE-techniques will help me stay retired AND do the planet a favor.
My father basically used his right to dispose of his property the way he thought was best for his loved ones. I don't see anything wrong with that and I don't see how the timing (before or after his death) needs to matter. Also, I can imagine how many people prefer to transfer stuff to their kids after their death, because as long as they live they don't know if they'll still be needing it themselves or not.
People will always invent arbitrary moral rules to deny other people pleasures or advantages (be it sex, drugs, rock 'n roll, or inheritances). But I prefer in most cases that those people apply them to themselves and not to others who don't subscribe to their moral system.
I'm not accusing Jacob of being jealous or mean, but if he doesn't want his interitance, he's welcome to refuse it. ;-) But please don't take away mine, because it is making my life much better, which was the intention of my father and making sure his kids had a better life was a big reason why he worked and saved so hard.
