If Bill Gates had $ 80 billion in the bank -LRB- let 's assume he put it all in cash -RRB- , would the bank be forced to print and give him his money if he requested it that way ?
Bill Gates donated about $ 28 billion when he was worth $ 50 billion . Now he is worth $ 80 billion . How does his net worth keep going up when he had parted with half of his fortune ?
