Daddy Dearest
Marie-Chantal can thank her father for her privileged upbringing. 83-year-old Robert Miller, whose investment business brought in $570 million in the last year alone, is recognized as the king of Duty Free after setting up a tax-free shopping destination in Hong Kong in 1960. His Duty Free empire quickly expanded (and gained the support of LVMH), becoming the world's largest travel retailer. (So you can blame him for all your airport splurging.)
