"America’s wealthiest 400 now hold a combined net worth of $2.3 trillion. That places the average Forbes 400 fortune at $5.7 billion, an all-time record high.
The richest of the 400 hold far more than that average. Take Larry Ellison, who just stepped down as the CEO of Oracle business software and holds the No. 3 spot. His net worth: $50 billion.
What does Ellison do with all those billions? He collects residences, for starters, with 15 or so homes scattered all around the world. Ellison likes yachts, too. He currently has two extremely big ones, each over half as long as a football field."
