Not to be totally argumentative, but is that true? I agree that beauty is in the eye of the beholder, but…
I looked up “value”; and none of the 15 or so definitions stressed individualism. On the contrary, the definitions revolve around value as a thing perceived by all; or a group of individuals.
In economic theory, value is something that takes at least two individuals to determine (one has to be willing to sell at a price; another must be willing to buy at that price). An individual, therefore, values something vs. what he believes others will pay.
I will agree, however, that emotion can affect an individual’s perceived value. If I am emotionally invested in something like my Father’s old Ford; I might find my perception of value to be distorted by my emotional attachment to the item. But that is not true value in the economic sense, since no one but me will perceive this value and be willing to pay for it.
I think the value that I was speaking about is the price/performance of the product. Trying to determine which is “best” seems pointless. Even if the Rally is better than the Protostar, its superiority must be weighed against the price; to arrive at a value judgement.
Do I like the Rally better? Yes, personally, I find it to be slightly more refined than the Protostar. But does that slight superiority merit the difference in price? That is where a consumer’s perception of value becomes important, especially at this moderate price point.
