If it was so then
why Jinnah & Iqbal were struggling for independent state, Economic exploitation can be stopped even in federal United India? Quaid has already put forth this solution in his Fourteen Points.
secondly What were the premises for the economic and political system of newly born state, Because we find a greater tendency in the both leaders toward Socialism and Social Democracy, But even then they supported the Democracy and sovereignty of all people, instead of Proletariat government?
If economic causes were of capitalist interest , then Jinnah was disloyal to History and Humanity both, Because it is accepted on all hands that the capitalist western system is welfare of few and exploitation of others.
Were Jinnah and Iqbal merely want to change our exploiters not the exploitation???
Thirdly, Jinnah by himself sharply criticized on capitalist system, He regarded it as the root cause of development of Fascism and Nazism in Europe.
Fourthly, if they didn't want both of these doctrines then what would be their vision regarding Pakistan?
