The Consumer and the Creator live and act at their own expense, which is why both of these personality types are variants of the Doer. At the same time, since people are more often Consumers than Creators, the Doer is more often a synonym for the Consumer.
The consumer is a beginner Doer. The Creator is an accomplished doer.
As ways of human life, the Romantic and the Parasite live and act at the expense of others, so both of these types are variants of the Parasite in the Agent-Parasite dichotomy. Considering that the word «Parasite» has a clearly negative connotation, and the Romantic aspires to high ideals, the label «Parasite» went to the Parasite itself as a way of human life.
Romanik is a bright personality with elements of parasitism. The Parasite is the Parasite.
