What technique is used when disparaging an opponent based on their material possessions?

The technique used when disparaging an opponent based on their material possessions is known as an Appeal to Prejudice. This strategy involves leveraging societal biases and stereotypes to influence opinion or judgment against someone. In this case, focusing on material possessions can evoke negative perceptions regarding wealth or status, suggesting that the opponent's value or credibility is diminished due to their possessions.

This technique effectively distracts from the actual argument or issue at hand, redirecting the conversation towards feelings of resentment or envy, which can sway the audience’s perception without addressing the core topic. By highlighting what one possesses or lacks, the approach attempts to undermine the opponent’s stance or character leveraging prejudice rather than rational discourse.
