Democracy is the rule of Majority. It is not relevent whether the majority is educated or illiterate. It is not relevent whether the majority is cultured or un-cultured. It is not relevent whether the majority is good or bad.
Out of 100 if 51 are blind then our ruler will be blind. That is the beauty of democracy.
Democracy is suitable to a nation where more than 90 % of population is aware what is good and what is bad for the long term national interest. Literacy doesn't meen enlightment or understanding rather most criminals and terrorist are educated. Citizens should be informed and inteligent enough to understand their interests and national interest in a long term.
Even in US where they have per capita income many fold of an average Indian they are not yet perfected in Democracy.
What about India and what about a backword state like UP.
