I think it is an inherent and natural trait which drives people to behave in such a polarised attitude.
Let us examine ourselves. Are we not more comfortable and cosy with people of our standards rather then the poorer of the lot? If yes, the rich and highly educated are also doing same thing.
Every one wants to be recognised in the society and that comes with only when one is above in the ladder whether it is show world or the area of education or business or high Govt post or belonging to a rich family.
When we enter a big gathering, we will generally be greeted by the people based on our status and if no one is talking to us or we have to start the conversation with everyone then it is very clear that we are the odd lot there and in such situation a feeling of dejection and inferiority complex has to arise.
It is human to feel hurted. Though some people are very prudent and patient and accept that they are the poorer lot and do not mind the whims and fancies of higher class and come back without being hurt or affected. Such people are few in the world and they will not ignore the less educated or poor people just because of that.
It may be difficult but let us try to become the latter type of personality.
Knowledge is power.
Definitely, we will be comfortable with people who are less educated and less rich than us. But the other person may think as if he is not fit in there. It is our responsibility to make them feel at home with us. This is actually what we should do. Similarly, when we are in the group where people are more qualified and rich we need not think about the difference but we should try to see what are the similarities. once you start doing that you will become more comfortable. When a chance comes in such groups we should show our talent and make the others also to understand our capabilities.
The human behavior tends to be different in different occasions & it's no denying the fact that what the author has put this is in the right perspective. There is a sense of natural reactions coming from within us, often these reactions may get observed by others depending upon their expertise & the level of maturity. Although, this is natural in all of us but most of the experts have come over this through practice & this is what we call being confident while removing their shortcomings during a span of time. Once the same was with me but now I have been able to control this to a greater extent but we can't completely be devoid of this.
In an example, the employee may feel a sense of uncomfortableness when faced by his employer. This is the practical scenario of my life.
Actually I yearn for such people who are not showy but broadminded. I feel uncomfortable to be with or around those who gossip and belittle others.
Beware! I question everything and everybody.
Friendship formation will not always be based on financial or educational status. Middle class or lower category people will be better friends, as far as my experience goes. Others may keep friendship but only expectings something back.
