As with most things, it gets more interesting when you consider the exceptions to the rules. For example, a lot of products have brand names that are significantly more expensive than the generic variety, though they are exactly the same otherwise, even made in the same plant, just with different labels.
A great example of this is wine. The same wine, made from the same grapes at the same winery, in the same bottles with no difference but the labels. It is so common that some wineries use unusual and unique glass bottles so that people know that “their wine is their wine”.
And a lot of discount liquors are just water, ethanol, and flavorings. A lack of choice and a lot of choice amount to the same thing, just fewer labels to choose from.
Fruit juices are usually deoxygenated to extend their storage lives, stripping them of their flavor, color and odor. Then “fruit derived” artificial flavors and odors and colors are added. Perfume dumped into pulp water. This is why different brands taste different, but always taste the same for that brand.
It goes on and on. Choice, or lack thereof, is just a marketing gimmick.
Remember “Two Buck Chuck”?
The wine was made with Napa Valley grapes rejected by the big names that were still far superior to many others; for $2 you could get a great bottle of wine (and the industry leaders were furious).
