You must be speaking in state regulators. The FCC, which regulated interstate long distance, had no such goal. The FCC required long distance rates to be as low as possible.
That was interstate service and so under the FCC's jurisdiction. An artifact was that in a large state the long distance rates, subsidizing local service, were often (usually) higher over considerable distances than interstate calls, which were regulated by the FCC. A notable example often cited is that the rate from Dallas to Phoenix (interstate) was lower than the rate from Dallas to El Paso (intrastate), although the distance to El Paso was less than the distance to Phoenix.
