The Hermès Family — $150 Billion

From a 1837 harness shop, six generations of Hermès family have built a $150 billion personal fortune, controlling 65% of Hermès International, worth over $250 billion in market cap. The Birkin bag's waitlist lasts years, with resale prices 3-5 times retail, reaching $500,000. The company never discounts, collaborates, or advertises much—scarcity is the core strategy. When Bernard Arnault secretly bought 23% of Hermès shares in 2010 (outperforming #2 Arnault's tactics), the family formed a holding company to force his exit. Old money fights differently: with patience, unity, and a refusal to sell out.
