First of all it needs to be understood why do we have these different classifications.Let us start with the recent case of introduction of computers in offices, banks,Rajya/Lok Sabha and now in the POST OFFICES.All those who have no computer education get terrorised by the very look of the computers and feel very threatened.The same thing happens in industries at the time of introduction of new machines and the workers go on strike.In our country,it has been the tradition that families follow professions which have come down to them from their forefathers and they are very comfortable with the known.Shopkeeper son knows all about running the shop even ifhe has not gone to any school.It is the most difficult thing to change profession even for the most highly educated.That exactly is the problem created by need to go for modern education so that the new generations can be trained to take on new professions for which jobs are going to be available in the times of rapidly changing technological environment.The children of school teachers generally dovery well because ofthe home atmosphere which is not the casewith the children of other professions.Hence,quotas are a must.
