Quote examples
John Bates Clark
American Economist
The market tends to pay as a wage what an individual laborer is worth. But the case last studied suggests the question how accurately the law operates in practice. May it not be an honest law, but be so vitiated in its working as to give a dishonest result?

Quote examples
George Orwell
British Author
All political thinking for years past has been vitiated in the same way. People can foresee the future only when it coincides with their own wishes, and the most grossly obvious facts can be ignored when they are unwelcome.

Quote examples
Pat Buchanan
American Journalist

Quote examples
Brigham Young
American Leader
Produce what you consume; draw from the native element the necessaries of life. Permit no vitiated taste to lead you into the indulgence of expensive luxuries, which can only be obtained by involving yourselves in debt.

Quote examples
Daniel Hannan

Quote examples
Maureen Dowd
