While the Progressives differed in their assessment of the problems and how to resolve them, they generally shared in common the view that government at every level must be actively involved in these reforms. The existing constitutional system was outdated and must be made into a dynamic, evolving instrument of social change, aided by scientific knowledge and the development of administrative bureaucracy.
At the same time, the old system was to be opened up and made more democratic; hence, the direct elections of Senators, the open primary, the initiative and referendum. It also had to be made to provide for more revenue; hence, the Sixteenth Amendment and the progressive income tax.
