Millionaires and Billionaires (What are the implications of this picture?)

One million dollars in $100 bills makes a pile 3.3 feet high (the size of a four-year-old child).

One billion dollars in $100 bills makes a pile more than twice the height of the Empire State building.

David Chandler, The L-Curve:

The red line represents a graph of family income across the US population. The height of the curve at any point is the height of a stack of $100 bills equalling that income.

The US population is represented along the length of the football field, arranged in order of income.

Median US family income (the family at the 50 yard line) is ~$40,000 (a stack of $100 bills 1.6 inches high.)

--The family on the 95 yard line earns about $100,000 per year, a stack of $100 bills about 4 inches high.

--At the 99 yard line the income is about $300,000, a stack of $100 bills about a foot high.

--The curve reaches $1 million (a 40 inch high stack of $100 bills) one foot from the goal line.

--From there it keeps going up...it goes up 50 km (~30 miles) on this scale!
