The National debt is the mortgaging of the property of our posterity that we may be better enabled to destroy our contemporaries.
The National debt is a deficit planned to teach the next generation the value of money by making them pay it off.
The National debt is a sure way to secure our younger generation against one indulgence - ancestor worship.
The National debt is like a crazy aunt we keep down in the basement... all the neighbors know she's there, but nobody wants to talk about her.
