I notice you reference Warren Buffet. 

"Warren Buffett earned $11.6 million in 2015 and paid taxes of $1.8 million. However, his net worth is $64.7 billion. That means in 2015, the world’s greatest investor only produced income of 0.018% of his assets. Is he slipping? How was his income so small compared to his many billions of dollars?"
