That's basically what Warren Buffet and Bill Gates have done, and I think that's a good idea.
Most charitable foundations that have been around for awhile are as bloated and inefficient as some government agencies, so Gates and his wife started their own foundation with about $40 billion and Buffet contributed another $40 billion to it.
Yes, they may or may not succeed and it's not clear that society will benefit from it, but I still think it's better than passing that kind of money on to heirs.
