The Heritage Foundation has an informative graphic:
Greg Mankiw compares the cut to a cup of coffee:
Just to be clear: $100 million represents .003 percent of $3.5 trillion.
To put those numbers in perspective, imagine that the head of a household with annual spending of $100,000 called everyone in the family together to deal with a $34,000 budget shortfall. How much would he or she announce that spending had to be cut? By $3 over the course of the year--approximately the cost of one latte at Starbucks. The other $33,997? We can put that on the family credit card and worry about it next year.
The Christian Science Monitor has more coffee analogies.
So why not mash them together?
How serious is Obama about fiscal discipline?
I don't know about believing in it, but that $100 million sure looks like change.
