if you dont want fighting and raiding over your stuff after you die then give it all away before you die.

Medical power of att'y, okay. Letting your family know your preferences on "when I'm gone", sure.

But for a Will - these days, what % of American adults are single, living alone, and have a negative net worth? Letting your family know that's the situation, and that they should stand back and let the gov't & banks to fight over your red ink, sound far kinder than leaving any of them stuck slogging through bureaucratic purgatory for nothing.
