Passage Summary: Wealth isn't good because good things never hurt anyone, but wealth definitely can.

Conclusion: Wealth cannot be classified as a good thing.

Reasoning: The definition of a good thing requires it to be entirely harmless, but wealth is known to cause harm to people.

Analysis: This argument relies on a strict, categorical definition to exclude a specific item from a group. It follows a valid deductive structure: if all members of group A (good things) must have property B (harmlessness), and item C (wealth) lacks property B, then item C cannot be in group A. When looking for a match, prioritize this 'all-or-nothing' exclusion logic. It's the classic 'if it doesn't fit the definition, it doesn't get the label' approach.
