“Anyone who lives within his means suffers from a lack of imagination” is a jocular saying that has been printed on many posters, where it is almost always credited to Irish author and playwright Oscar Wilde (1854-1900). Wilde never said it.
 
Lionel Stander (1908=1884), a Bronx-born actor who had many marriages, said the quotation in an interview with Playboy magazine (December 1967). Stander was credited for the quotation until about 2000, when the false attribution to Oscar Wilde made the quote even more famous.
