Role of politicians
I am sorry to inform you that Bangladesh emerged with the legacy of economic exploitation for almost two hundred and fifty years. The Politicians, Civil Servants and Military Leaders in Independent Bangladesh came from the families (usually large) where economic hardship was seen as "Shame ". So during the tenure of "Democratic Government" or the "Martial Law Government" it was found that people in the government became influential persons either through exploiting power or accumulating wealth. They have never done for the nation what was expected of them.
