“Here are some other metrics for understanding the size of the national debt and United States borrowing:
* U.S. Treasury Secretary Timothy Geithner has said the United States borrows about $125 billion per month. With that amount, the United States could buy each of its more than 300 million residents an Apple Inc iPad.
* In a 31-day month, that means the United States borrows about $4 billion per day. A stack of dimes equivalent to that amount would wrap all the way around the Earth with change to spare.
* In one hour, the United States borrows about $168 million, more than it paid to buy Alaska in 1867, converted to today’s dollars. In two hours, the United States borrows more than it paid France for present-day Arkansas, Missouri, Iowa and the rest of the land obtained by the 1803 Louisiana Purchase.”
