Abstract The life and the works of Jack London depict his struggles to bring a radical transformation of American culture like Sinclair Lewis who satirized the “Main Street mentality” and “Babbitt culture” spreading like a destructive virus in America. Jack London expressed his commitment for the the socialist movement to uproot the capitalism of America. He belonged to the grass root level; he had worked in mills, factories and mines and had seen the oppression of the rich people. He got the first emotional shock when his beloved Mabel Applegarth deserted him and he started hating the upper class values. He had innate sympathy for the working class and as a proletarian; he desired to be a part of the Cultural Revolution. London possessed exceptional gifts which could lift him out of his class. But his passion for socialism infused in him a strong enthusiasm to bring drastic change in the contemporary America. His drive for material prosperity put him in dilemma; on one hand he was a committed socialist and on the other hand he desired to be rich to escape the hell of poverty and hunger. Jack London continues struggling in life and continued writings novels to articulate his passion for the cause of socialism and to bring the cultural transformation. London realized that the poor and the proletariats are weaklings and the weak have no place in the cruel oppressive system; they have to organize themselves with to fight with the oppressive forces.
