teenagers are very insecure in their own look and status and they need to latch onto trends to give themselves security and an identity.
individuals want an accurate assessment of their opinions and performance, and that in the absence of objective standards, they look to others (preferably those who are similar in a relevant dimension) for information about their relative standing.
Festinger, L., A Theory of Social Comparison Processes. Human Relations, 1954
His first hypothesis is that in humans there exists a drive to evaluate his opinions and abilities by comparison with the opinions and abilities of others. Both opinions and abilities have a strong impact on his behavior. People want to know how their abilities stack up against others. Some abilities have clear criteria (e.g., running times), others are actually an opinion themselves (when there are non-social means of comparison available). People also don't tend to evaluate themselves against others that are too different than themselves. In fact, given a range of people they will choose people most like themselves for comparison. Also, a discrepancy in a group with respect to opinions or abilities will lead to action by members to reduce that discrepancy.
One website, Social Conformity and Violence, states that "Conformity can be defined as a change in a person's behavior or opinions as a result of real or imagined pressure form a person or a group of people". It goes on to say that a key part of group conformity is compliance, the "behaviour of a person motivated by desire to gain reward or avoid punishment".
A private necessity might be a washing machine, and a public luxury could be a luxury car. The most common type of public luxury is the car. It has been stereotyped and personalities have been judged on them for years. An article in the Telegraph says "sociological research has revealed that the population at large does draw conclusions about the personality of car owners from their vehicles. The longer the bonnet of a car, the more arrogant and macho the driver is judged to be. The larger the boot, the less youthful the owner". And the car industry feeds off this seemingly innate judgement. One of the most common theories for this phenomena is that it is an easy way of comparing your success against those around you. If you park your car in the company car park you can immediately gauge your car against that of almost everyone else in that company. If you park your car on your street you can see straight away how it sizes up to your neighbours. But if you really want to know what your car says about you, read Forbes' analysis.
