Propeller planes used about half as much fuel per mile as early jets. Jets have caught up, but it took half a century to get back to earlier levels of fuel efficiency.
Slowing down in general is an easy way to bring down energy usage, but it's often a hard sell.

basically true, but speed isn't the only reason why jets have dominated; being able to fly above the weather, noise, and (perceived) safety are factors too.
