Evil Twin Pricing?

In the simplest terms, human beings, regardless of their means, are more likely to purchase expensive items because the perceived increase in value stimulates greater pleasure from the purchase (dopamine release and the like). This is the flaw in the invisible hand doctrine, and is doubly true for substances like alcohol which breed even further mental dependency. Purchases made by the consumer don't accurately reflect demand because people are not cold, logical creatures. Emotion, illness, addiction, etc. all skew the field.

I don't entirely understand people who say "don't like it, don't buy it" because if it was really that easy, countless businesses and institutions in this country would long have gone extinct. Criminal banks, for example.
