Passage Summary: A politician claims we should ignore union leaders' warnings about multinational companies lowering wages because those leaders benefit from high wages and are therefore biased.

Conclusion: Legislators should disregard the arguments made by union leaders regarding multinational manufacturing control.

Reasoning: The union leaders have a personal financial interest in maintaining high wages, which motivates them to persuade legislators to oppose multinational control.

Analysis: This argument commits a classic source attack, also known as an ad hominem flaw. The politician focuses entirely on the union leaders' motives and potential bias rather than addressing the actual evidence or logic of their claims. Even if someone stands to benefit from a certain outcome, their factual observations about global wage trends could still be entirely accurate. Look for an answer that identifies this failure to address the substance of the argument instead of the person making it.
