In spite of that, due to historical reasons ultimately modern industrial undertaking began to take root in India. The flow of surplus British capital began to be invested in India in different sectors. As a result, with the growth of modern industrial undertaking wage earning working class came into existence in India. They were mercilessly exploited having no rights whatsoever.
