And I see no indications there will be a pile of money for my kids once I die. So, intellectually, it's easy for me to agree with you.
But if by a turn of events my life transforms from being a financial disaster into a money-making success story and I end up with money at the end, I would like to give them what I feel every human being should have: a chance to find themselves, to find out what they are good at and what they love, without wrecking their finances. Because you only live once and you should try not to give your small amount of hours on earth to someone or something you do not believe in. So I would like to give them each a little "go and find yourself" fund that they could utilize once they're, say, 20 or 30 years old.
That feels wrong, intellectually, but if I have money and we haven't yet scrapped the notion of inheritance, then there will be "find your true you" funds for my kids. No doubt. Because if my kids find what they're really good at, they'll kick your kids asses ;)
That's what life's all about right? Setting things up for your genes. Bootstrapping your gene carriers lives, not with money in particular, but with the things they'll need to out-perform the rest or more importantly, to be as happy as they can be. Anything else we do with our time are just hobbies.
