Didn't realize the phrase only became popular in the '70s.

The thought may be Stone Age but the phrase 'if it ain't broke don't fix it', which sounds as though it might come from the Roosevelt or Truman era, is more recent than that. This one is widely attributed to T. Bert (Thomas Bertram) Lance, the Director of the Office of Management and Budget in Jimmy Carter's 1977 administration. He was quoted in the newsletter of the US Chamber of Commerce, Nation's Business, May 1977:

    Bert Lance believes he can save Uncle Sam billions if he can get the government to adopt a simple motto: "If it ain't broke, don't fix it." He explains: "That's the trouble with government: Fixing things that aren't broken and not fixing things that are broken."
