I firmly believe a lot of the "Mega Rich" well the ones who haven't inherited it (I'm looking at you Walton children) don't make money because they want to be "rich".
They make money because they are good at it and they find it fun.
To Warren Buffet, making billions of dollars is = some gamer trying to get the high score on a Ms. Pacman machine in their local pizzeria, someone trying to get the lowest time they can on GT4 or unlock 100% on a RPG.
Look at Bill Gates, who has billions of dollars, plans to give it all away and yet is still making lots of money. He wants to spend pretty much all of his money before he goes by giving it away to charity yet he's still making it... why? He's gotta have a reason to go through all the crap and still work when he could retire.
As for should they give it away? Sure, maybe. Then again i'm sure some would like their kids to be rich and also make it so that their grandchildren will be rich too... and knowing their granchildren they may want there granchildrens kids to live better too... etc down the line...
Sure that seems like a lot of "Looking into the future" to connect those distant descendants, but then again to get super rich isnt that the quality you need the most?
