Again, you are not getting the point. The discussion is around barbers as a whole trying to charge a very high price when the market is not that. Who cares that some barbers have rich clients when the vast majority of barbers have middle class clients.
All you are going to do is push the vast majority of people either to find a cheaper barber, get their hair cut less or to cut their own hair. That is not sustainable for most barbers and you can not argue against that. That would be like restaurants charging out the ass for food, driving people away to other restaurants or having them cook at home. There may be some restaurants that can set high prices and work but that is not smart for every other restaurant and that shyt will put you out of business.
