Scarcity advertising is, for example, "Joe's grocery now has cantaloupes" (back in the day when cantaloupes were not available all year). It's information - something is now available that wasn't available before.
Abundance advertising is, for example, "The Chevrolet SomeHotCar will give you an exciting life like the people in this ad. Don't you want that?" As someone put it (wish I remember who, I would give credit): "[This kind of] advertising attempts to make the person you are envy the person you could be with their product. In other words, it attempts to steal your satisfaction and then offers to sell it back to you."
The first kind of advertising is useful. The second is abusive.
