In the broadest sense of the word, snobbery is an emphasized belonging to a certain social or professional circle of people. This affiliation is manifested in everything: in clothing, actions, speech, posture, gait, etc. Moreover, the range of interests, to which the snob considers himself, is almost always informal. This means that snobs are engaged in self-aggrandizement, they often do not take into account the opinions of other people, and their behavior is arrogant and pseudo-aristocratic. In addition, snobs for some reason consider themselves to be an elite, although in reality (among other professional and social groups) they are most often treated with condescending scorn. People simply understand that snobbery is just a non-standard statement about their moral qualities, which has little in common with ethical standards.
Snob is proud to be a member of his "elite" circle, and therefore, by all means, by hook or by crook, protects him. Another thing is interesting. Initially, it was believed that snobbery was an affiliation with the non-aristocratic class, the ability to "squeeze" into a circle of people of noble birth. Such people were calculated right away - you won’t learn exquisite manners in five minutes or even five years. In this regard, snobbery is also an insult to the conservatism and power of the aristocratic class.
On the other hand, our current attitude towards snobbery and snobs may be more lenient. A man dresses well, he has excellent manners, he knows how to behave in a decent society. Ultimately, it makes a pretty good profit. You must admit that snobbery is not a cheap pleasure. The question is, what's wrong with that?
Of course, nothing. Except for one point: narcissism. Self-love, in whatever form it appears, has always been annoying. Especially if at the same time someone is trying to teach others how to live! But snobs, unfortunately, have such a sin. Emphasized dissatisfaction with everything that happens often turns into moralizing.
In addition, snobbery is a definition of human actions, sometimes a polite definition of cultural and even moral decline. A person who is credited with individual snobbish qualities may not actually be a snob. However, he may behave in an “improper manner in a decent society” manner, “speak arrogant speeches” or contrast himself with others. In any case, we are talking about disrespect for others, turning into a dismissive-condescending tone with the outside world. Snob, as it were, puts on gloves and is afraid of getting dirty in some way. Moreover, he constantly emphasizes that he is forced to communicate with people not interested in him. Thus doing them a favor.
This is precisely the main problem. When we say what snobbery means, we mean that people of this kind do not create and do not support the existence of values. They take advantage of the moment created by other people, but they themselves do not try to create anything. Aristocrats, at least, created a world in which everyone lives - this world is open and accessible. A snob "closes" in his own little world and does not want to understand and see other people.
