There's no such thing as "real value" in this world. Each person perceives value differently, and the nearest thing we have to an "objective value" is market value, determined by concrete factors like demand and supply.
One can not place a “real” value over a product or a service as we all have different perceptions of that product or service depending on our social and economic conditions. One can think that product a is too expensive for he or she does not really need it nor see any value for it. However this doesn’t mean that that product is completely worthless already. One can still appreciate its value for he or she actually needs it.
Social trends also matter in this context. Whatever is trending will be perceived more as valuable and thus the need to increase the price will be likely.
