In my opinion middle class, in every society, always proves itself an agent of change,be it positive or negative.Hence, there is no denying the importance of this class.A thriving and awakened middle class lends a helping hand in the development of a country.Moreover, it is a generally recognized fact that middle class is more sound morally and ethically as compared to upper or lower class.So, aspirants belonging to middle class SHOULD do css.

One more thing that we SHOULD shun now is generalizing the things. There is no set criteria for ANYTHING in this world.A person belonging to middle class may be corrupt and a person of upper class may possess a strong conscience guiding him on his way to life.
