India middle class have travelled a long way since late 19th century when they bow the seeds of freedom movements.They wrote a unique documents for the new nation-The constitution of republic of India.Evolving the middle class will positively strengthen the India economically,socially,politically as most of the important first think tank initiative has been taken from the middle class since the time of independence to the 2012 dreadful rape agitation.The middle man has an eye on the both side of the coin.however, India middle class is now harden to the world out side its own class,Class work on the theory of relative deprivation that create in selfish motive and more the class act like a community and rise a situation of us vs they.but strengthen middle class is more like giving more economic and social strength to nation as they will produce teacher,doctor engineers,writers and more intellectual.
