What is wealth and what is a man's worth?
If we piled $100 bills - 5 reams (2500 sheets) would equal about one foot high.
Imagine we took a pile of money equivalent to less than the fortune of either Gates, Buffett, etc. - $50 billion - and started to make a stack of $100 bills that stood aside the Empire State Building.
The money would not run out when we hit the roof - 1250 feet above the street.
Nor would it run out at the second pile. Or the 10th. Or the 100th.
At the end of the 160th pile of $100 bills, each side by side, reaching 1250 feet high, we would finish our task.
The median American's family money pile is less than 3" high of the same $100 bills, far short of the 200,000 feet of just one of the super rich.
