> they contributed some of the billions in previously captured profits from their family wealth to get to an agreement Not even that. They agreed to give 4.3 billion dollars over the next 9 years. Given how much net worth they have, over that 9 years they will earn that much, or more, in interest. They're just giving up the next 9 years of growth, they'll still be multi-billionaires.
