Agree.

Stretching the concept a little more:

We should understand that lift is not some magic thing that keeps airplanes flying and gliding, the force of lift is proportional to the work that the wing performs on the mass of air.

In other words, in order to be lifted by the air with a force enough to sustain level flight, the combination engine-wing must give an equivalent amount of energy away to that air.

The airplane acomplishes that by forcing its way through the air overcoming the draft forces (due to friction and lift).
