Hard to tell if you are serious. My mother and father are going to leave me a bit of cash from their business earnings (I wish they wouldn't). That doesn't make me a Rothschild or a Hearst. Not to mention regal dynasties or modern tech entrepreneurs which are in another category entirely.
I suppose you could say that, although by US standards I'm far from "elite". Generally I think people should focus on maximizing their "life happiness". It's not my parents responsibility to scrimp and save to make my life better after they have passed. I would much prefer they spend their time and money enjoying their time here. I'm not suggesting they spend zero on me, I'm just saying they should not be unnecessarily frugal their entire life for my benefit. Obviously there are trade-offs. They have helped me in many ways (as parents do) which has contributed to my high quality of life. I'm suggesting that they enjoy the remainder of their lives as they wish.
While I can't speak for him, in my case it's because I want my predecessors to reap the benefits of their labours and spend their money on themselves before they die. As I say to them (and others), you only get one life and there are no prizes for checking out with money left in the bank.
I had this conversation with my parents recently as I share a similar view to the parent comment. My father has made a decent amount of money from his successful business, but by far the greatest proportion of their wealth is tied up in various property assets. They put this fortune down to good timing vs being "earned" in the same way as the business profits, and believe it should be something that future generations in the family benefit from. They travel internationally multiple times a year and assure me they will continue to enjoy the good life for as long as they can, but they're adamant when it comes to their plan to leave a meaningful estate for the kids and grandkids.
