The evolution of Mumbai from the British period to the post independence period with trade union movements, was followed by a shift to politics on the basis of getting jobs for local Marathi people in what was once the commercial capital of the British Empire. This kind of politics was led by Mr. Thackeray after 1967. As this report in The Hindu says Mr. Thackerayand the party Shiv Sena highlighted the plight of unemployed Marathi youth  through his party's weekly Marmik. The first government of Mr. Thackeray's party was formed for the state of Maharashtra which includes the city of Bombay by Manohar Joshi in 1995. 

Both the trade union movements of Mr. Fernandes in Mumbai and the ethnic politics of Mr. Thackeray failed to provide the development needed for the state of Maharashtra because of the lack of the technology and capital needed and the knowledge of industry needed that could be applied on an American scale, much like the flawed efforts of Mao's politics in the Great Leap Forward, and the Great Proletarian Revolution in the post 1960's period.
