Parallelism (also referred to as parallel structure or construction) is the use of two or more phrases or clauses in a sentence that have similar or the same grammatical structure. It has multiple purposes - to give balance, clarity, pattern, or rhythm.
The given sentence contains several clauses in which parallelism is obvious. They begin with the word <em>who </em>and present simple tense (<em>who prefers, who (constantly says), who (pathetically) believes, who lives, who (constantly) advises</em>).
