Why does prestige pricing signal high status and quality?

"value is called prestige pricing. This type of pricing is common where high prices indicate high status. In the specialty shops on Rodeo Drive in Beverly Hills, which cater to the super-rich of Hollywood, shirts that would sell for $65 elsewhere sell for at least $150. If the price were lower, customers would perceive them as being of low quality. Prestige pricing is also very prevalent in services because services providers with reputations for excellent service are more in demand, often with a waiting list. This is due to the fact that services are tied directly to the people who provide them and those people have only so much time in a week in which to provide services. Once the calendar fills up, the demand goes up, and the prices become prestige prices."
