Luxury or necessity 

I have my subjective opinion about this question.I think yes ,where is some kind of barrier between  luxury and necessity.Ordinary human has some needs and desires ,that have steps.At first person wants to be  physically and socially satisfied.If a person doesn't earn much money ,how he can think about luxuries ? Nowadays people in countries like Armenia think how to feed themselves.In the case that person has this first step of being  dressed and satiate he willthink about luxuries.I think it is also  a salary matter.For example if someone has small wage,he will decide how to save money and buy  cheaper goods,but when  someone has a good salary,apartment ,he will think about eating bioproducts,wearing expensive and well-known brands clothes.When the first step is absolutely  completed a person will suppose of how to make an impression on people.For example some person is a general director of some company,he doesn't even need of  luxury car,but he buys it to show that he has money,he works  for expensive company,when he enters some  cafe and waiters see his car they guess ,that their client is quite wealthy ,so the service must be good.People  start to think about their status in the society,are they respected or not,so luxury is one of the best ways to show that.This is just a simple psychology of humans.
