Sorry, but when one-third of your income still allows you to pay for mortgages and property taxes on estates totaling over $87 million, I still think that's an absurd amount of wealth to hoard away for one family.
I don't get why it's such a concern as to what they spend their money on when they give MILLIONS upon MILLIONS of dollars to charity. The argument that "it's still a small percentage of their income" is absurd to me.
