   • 1960 April, “Talking of Trains: The U.S. commuter problem”, in Trains Illustrated, page 201:

     [...] to make commuter operations profitable, a 70 per cent fare rise would be necessary. The president admitted that an increase of this magnitude would be self-defeating and suggested that the commuter himself should not have to bear the whole burden because the service was not exclusively for his benefit, but largely for that of the community concerned.

   • 2022 March 23, Paul Clifton, “Londoners pay the price”, in RAIL, number 953, page 49:

     The strike will win few friends as the capital tries to woo commuters and shoppers back after the pandemic. And the fewer the people using the Tube, the lower the fare revenue. The lower the fare revenue, the sterner the job cuts could be. Many people therefore see the industrial action as self-defeating.
