What does Rauschenbusch urge Christians to do to alleviate poverty?

Mr Rauschenbusch proposed what was called the social gospel and he imposed the responsability of Christians to be good toward others. After stating that we live in a immoral economic system, he said: " To create just and brotherly relations between great groups and classes of society; and thus to lay a social foundation on which modern men individually can live and work in a fashion that will not outrage all the better elements in them"
