"In reference to the Prussian three-class the views of many of the s had in the course of time undergone a change. It had escaped the memory of some of them, here and there, that the logically and cunningly realized purpose of the three-class electoral system was to exclude with hermetic sealing all democratic thought and sentiment, and that the capitalistic era, which began about the same time with the introduction of the “most wretched of all electoral systems,” had by creating a class conscious proletariat rendered the vote of the socialist masses more insignificant than the vote of the democratic masses had been originally. How badly many of the speakers (both men and women) at the Hamburg convention deceived themselves as to the working of the three-class electoral system is clear from the fact that some of them entertained the delusion that the reform of the legislative elections could be used as the means of a grand arousing of the masses. In the jubilation over the success which had been achieved under other non-democratic laws regulating legislative elections, especially in , many had forgotten that the Prussian three-class system made the publicity of the ballot obligatory, and thereby in advance practically disfranchised all who were dependent, either economically, socially or politically, that is, the great majority of the population, and by this means alone rendered it impossible for the masses to take part in the election or get up any general enthusiasm."
