Logic Breakdown

Passage Summary: A politician argues against stricter pollution rules because they would kill jobs, and we aren't sure if the cleaner air is worth the lost paychecks.

Conclusion: The government should not increase the current air quality standards for industrial emissions.

Reasoning: Raising standards would drive industries to move elsewhere, causing job losses, and there is no proof that the resulting environmental benefits would outweigh these economic costs.

Analysis: The politician is making a value judgment based on a cost-benefit analysis. To justify this reasoning, we need a principle that acts as a bridge, specifically one that favors the status quo when the benefits of a change are uncertain compared to the definite costs. Look for an answer that suggests a policy should not be enacted unless its benefits are clearly shown to exceed its negative impacts. The argument assumes that protecting jobs is a priority that should not be sacrificed for unproven environmental gains.
