Only 22 families from West Pakistan controlled 66 percent of the country‟s industries, 79 percent of the insurance companies and 80 percent of the banking organization. This picture showed glaring example of disparity in economic sector of Pakistan. Cultural factor The culture of two wings was distinctly different. By historical background, landscape, rivers, poetry and music East Pakistan was a distinct region. Cultural and social practices of the people of East Pakistan are diametrically opposite to those of West Pakistanis. In spite of distinct differences the ruler in Central government, which was dominated by West Pakistanis, had made an attempt to impose Urdu as the only language 4 Economic issue The economic exploitation remained a weapon in the armory of the ruling class to curb the voice of the common people in the under developed countries in particular. From the economic point of view, East Pakistan remained neglected. The people of East Pakistan felt that their region was being exploited to mobilize their resources to serve the interest and needs of the people in West Pakistan. For example, East Pakistan had a favorable trade balance with foreign countries during 50‟s and 60‟s.On the other hand; West Pakistan ran a deficit foreign trade balance. East Pakistan earned about 60 percent of country‟s foreign currency while she received less than 30 percent of imports. Jute, jute goods, tea enjoyed world markets during Pakistan period. A constant deficit in trade between the two wings was the fact of exploitation. This clearly indicated a transfer of East Pakistan‟s resources to western part of Pakistan. This also demonstrates the fact that East Pakistan served as the captive market for the industries of West Pakistan. Agriculturally, West Pakistan was not developed but with the construction of gigantic Mangla and Tarbala dams, huge land mass came under irrigation system and subsequently, agriculturally west wing developed enormously. No such step was taken for the agricultural development of the East wing of Pakistan except Kaptai dam for producing hydraulic power generation. Only dam was in East Pakistan.
