Actually I believe the House of Saud aka Saud Family (in Saudi Arabia) has a well known estimated net-worth of over 1.4 Trillion.
15000 people in the 99%-99.9% would have about 120 billion. 15000 people in the 99.9%-99.99%? They'd have about 600 billion. The top 0.01% has about 6 trillion.
So, it's a family of 15,000 99.97%ers!
