Perfect example of a negative spun into a positive.
A combo of carrot and stick: illustrating what other experiences look like while simultaneously promising the opposite.
The entirety of the ad is offering evidence that points towards the main seed being planted: “We have to try harder, and you benefit.”
Back-to-back setup-punchline couplets to finish off the ad.
