Plutology is a rather uncommon word, and as such, it can be difficult to find synonyms that convey its meaning. The best possible synonym is probably the word 'wealthology'. This word describes the study of wealth or the distribution of wealth, which is essentially what plutology means. Other possible synonyms may include 'economic power analysis', 'distribution of wealth studies', 'riches analysis', or 'money distribution research'. Ultimately, the concept of plutology focuses on the study of wealthy individuals and their impact on society, so any synonym that touches upon this idea should suffice.
