You would think that once you have attained sufficient resources to satisfy a specific need that, once satisfied, you would then redirect excess resources to a different need. For example if you needed a healthy snack and wanted to eat an apple, once you ate an apple or two you would be satiated and stop. Instead you would then look to your other needs, if you were still hungry, such as a sandwich, to balance out your meal. It would be illogical to simply keep searching for and buying various different apples for the sake of variety and interest. In my simple view that is not what I see in the world.
