After someone asked Warren Buffet why he wanted to give away all of his fortune, he replied: "I want to leave enough money to my children that they can do anything, but no so much that they will do nothing".
The British entrepreneur and investor Peter Jones also worried about that problem and decided to double any money his children earned for themselves.
Whenever I wish I were super-wealthy, I try to remember that super wealth probably just creates all sorts of problems when raising children. If I ever do get super wealthy I'll plan to spend all but a few million dollars, secretly and out of sight of the children, before they reach the age of twelve, so that I don't have to worry about them growing up with the typical rich-kid problems.
