Hopefully they will leave something in case one or more of the kids "fall down" later in life. I think Bill and Melinda might be discounting the luck factor that they have had in their own fortune. While I'm not saying that they didn't work their butts off to get where they are, there was a lot of luck involved as well. Imagine how they would feel if, after they were gone (and I realize they can't feel anything at that point...), one of their kids was in their 50's and lost everything because of bad luck - cancer or other disease for example. Then the "kid" had to live his/her life out in poverty. How sad would that be that he/she had the richest parents in the world (due to good luck) but lived in poverty because of bad luck.
