Hundreds of Industries left W.Bengal during 1965-67 because they could not get any contracts/license/permits/foreign exchange from the Central government unless they move out. That was the level of discrimination against West Bengal since 1950. Refugees from East Pakistan could not get any compensation, they were forced to live in Transit centres for repatriation back to Pakistan according to Nehru-Liakat Ali Pact. Then everything were transfered from West Bengal( State Bank, LIC, General Insurance, Geological survey, Zoological Survey). Weast Bengal was categorised as Developed State so no planned investments came to West Bengal. Durgapur steel was the last as a compensation for the loss of State Bank. Air-India does not touch Calcutta since 1966. Foreign exchange earning, natural resources, and tax revenues of West Bengal and the whole of the Eastern India was used for the development of the Western and Southern states Due to this discrimination West Bengal went down, but after the removal of the license/permit/quota Raj , now all investments are coming back. However, still there are discriminations regarding taxes against industries located there. West Bengal was totally destroyed in 1965-67 because of Morarji Desai, Jagjivan Ram, YB Chavan, SK Patil, Bhutalingam, etc, etc.
