She has an ego because, she is beautiful. He has an ego because he is rich.Notice that the ego associates itself in these words to make the individual feel big about himself/herself.People get really wild and uncontrollable when they have an argument(at least I do this). It is because, the ego of these individuals is not able to take it when the other ego is suppressing it (remember ego ,likes to grow big). That's why if you see in most arguments there is never a winner , on second thoughts there is always a winner , the Ego.
There are some others who make fun of themselves and enjoy it .The actual intent in some of these people is to hurt themselves ,before others get a chance .A defence mechanism to protect the ego.Lets take physical appearance as a way in trying to understand this .Some people are not gifted in terms of height .They would say , if only i was more taller or fairer or thinner (list goes on) .What they expect is the friend to tell that they are wrong and he/she is actually tall enough or not that short.This way they avoid being mocked at and more importantly ,they give a chance for their ego to grow.Ego generally thrives in support and appreciation
The I, come to think of it is just another form of ego.The I always thinks its right and when someone opposes it or does not agree with it .It gets hurt and directs the individual to do something that will make himself/herself feel even bigger.
I have been hearing right from my childhood ,saying that middle class people are the people most likely to get more spiritual and religious or people with good moral values .This would make me feel privileged to an extent ,as I identified that I also fall into the same category .100s of reasons by family and friends saying that the poor people cant think of anything other than food and shelter ,planning for mere survival and the rich are easily corrupted by unwanted pleasures.This made sense to me and still makes to an extent . More and more I wonder , is it really true ? or is it because I,my friends and my family all identified ourselves to the middle class group ?I certainly havent heard any poor or rich person sharing the same sentiment.
