I know the government takes it from my pay at the speed of light.
Hahaha, that’s funny ;)
But velocity of money is a real thing:
http://en.wikipedia.org/wiki/Velocity_of_money
It just means how many times a given unit of money will be used over a certain period of time. So when Nancy Pelosi says that $1 of food stamp money creates $1.79 in economic activity she means Food Stamp Recipient A spends $1 for food at Store B who then takes that dollar and spends $0.50 from Supplier C who spends $0.25 on whatever else. The numbers are made up just to illustrate the point that the comment Pelosi made wasn’t really that dumb.
