I was puzzled by this sentence in the article: "A much wealthier family with homes and assets in multiple countries and currencies might require more cash flow management,
customized financing for mortgages, yachts or planes, and the ability to borrow against art or investment portfolios." If someone has liquid assets worth well over $25 million, why are they borrowing to make entirely discretionary purchases?
They might want to read the following book, in which the author relates receiving a large windfall, hiring managers to look after it, and eventually having to declare bankruptcy due to the professionals' incompetence.
No one worries about your money more than you do!
