I think most people would be thrilled to simply pay off their current home, pay off student loan debt, contribute significantly to their retirement, help their children pay for their education & get into their first home. Maybe this falls outside the realm of "significant wealth" but that type of security would sure make a lot of people happier by easing day to day financial stresses.

Now, I can definitely see issues with enough money to essentially buy whatever a reasonable person could possibly want, depending on the recipient of a real fortune. But in general parents who have been fiscally responsible and not flashy with their money don't have a bunch of kids who think differently about money. So even if a lot of wealth is inherited the children will manage it responsibly for the most part, though there are always exceptions.
