No, see, Dio - who, as a vampire, is associated with the aristocracy, in spite of his own low birth - co-opts a symbol of blue-collar workers (steamroller, associated with construction), which signifies his repression of his own base roots and subsequent privileging of the aristocracy over the lower classes. But even that is not enough to help him prevail against a truly wealthy aristocrat, in the person of Jotaro, who not only comes from a noble British lineage but who has the wealth embodied by the Speedwagon Foundation. Therefore, Dio represents the eternal but vain struggle by the proletariat to join the aristocracy by repressing their brethren.

Hirohiko Araki...like Karl Marx, in a way.
