The outlook of the Preamble is embodied in "Solidarity Forever", which enunciates several elements of the IWW's analysis. The third stanza ("It is we who plowed the prairies") asserts the primacy of the role of workers in creating values. This is echoed in stanzas four and five, which provide ethical justification for the workers' claim to "all the world." The second stanza ("Is there aught we hold in common with the greedy parasite") assumes the two antagonistic classes described in the Preamble. The first and fifth stanzas provide the strategy for labor: union solidarity. And the sixth stanza projects the utopian outcome, a new world brought to birth "from the ashes of the old".
