“Spending money you don't have for things you don't need to impress people you don't like.”
Quoted as "Actor Walter Slezak's version of "keeping up with the Joneses"": in LOOK magazine, Vol. 21 number 14 (July 9, 1957) p. 10 http://books.google.com/books?id=-NERAQAAMAAJ&q=%22impress+people%22, in LOOK's permanent category of quotes "WHAT THEY ARE SAYING".
Already in 1905 W.T. O'Connor had stated that advertising was "The gentle art of persuading the public to believe that they want something they don't need" in "Advertising Definitions", in Ad Sense, Vol. 19, No. 2 (August 1905), p. 121 http://books.google.com/books?id=zPRKAAAAYAAJ&q=%22W.+T.+O%27CONNOR%22, and in 1931 one finds Will Rogers being quoted with advertising "as something that makes you spend money you haven't got for things you don't want." But this complete statement with the finale "to impress people you don't like" seems to have originated with Slezak. However, Quote Investigator https://quoteinvestigator.com/2016/04/21/impress/ instead traces the quotation back to American humorist Robert Quillen, who wrote in 1928: "Americanism: Using money you haven't earned to buy things you don't need to impress people you don't like."

“Money poisons you when you've got it, and starves you when you haven't.”
