Not all of the world's billionaires are dedicated to being extraordinarily altruistic — many decide to spend their money indulging in fancy cars, planes, and yachts.
But others want to spread as much of their wealth as possible before they die. A select few even want that last check to only cover the cost of their funeral.
Of course, not everyone stands to gain from such selflessness — namely, the children of these generous donors.
Though they will still have untold opportunities, advantages, and connections, to help them succeed, the children of these 15 tycoons won't be living large off their inheritances.

1. Business magnate Warren Buffett
As an incredibly wealthy investor and philanthropist, Buffett has pledged to give away 99% of his wealth, either during his life or when he dies. He started by promising 83% of it to the Gates Foundation, according to FORTUNE Magazine.
The Oracle of Omaha isn't worried about his children not getting their fair share. Echoing a common sentiment on this list, Buffett said in his letter to the Gates Foundation: "I want to give my kids just enough so that they would feel that they could do anything, but not so much that they would feel like doing nothing."
