The Reason Behind nair caste Became Backward???

Here am discussing the basic reasons behind the fall of nair community,and how they became in a present situation:

1. nairs  lost their near position in Army even during 19th century when the British started recruiting others also. The British took away right of Nairs to wear arms.
2. nairs used to cultivate mainly food grains (paddy and other grains) and coconut and land reforms were implemented on such lands. The lands where cash crops were cultivated known as plantations were exempted from land reforms and therefore minority communities who mostly owned them did not lose it.
3. nairs  considered trading as something not befitting them and minorities and Ezhava community who did trade profited out of that. During the rise of communism in Kerala the left parties mainly targeted land owners and not the rich traders. So it was mostly  nairs  who suffered. 
Kerala’s development from 19 th century mainly meant trading developed. Kerala does not have many industries. Since very few nairs were traders and development of trade did not benefit nairs much.
4 Though nairs learned from the example of Christians the benefit and strength of Organisation forming nair Service Society (nss), they failed to implement careful planning in their operations and could not resist social changes which went against the community. Even the political power wielded by nairs was soon lost. While nss wound up its political arm NDP, Kerala Congress which represents Christians and Muslim League which represents Muslims have become more powerful.
