A country is experiencing a severe economic downturn, characterized by rising unemployment and a sharp decline in consumer spending. The government is debating a large-scale fiscal stimulus package that includes direct cash payments to all households. Two economic advisors offer conflicting advice:

• Advisor A argues: "This stimulus is exactly what we need. Because so many people are struggling financially, they will immediately spend this money on necessities, creating a powerful and immediate boost to economic activity."
• Advisor B argues: "This is a mistake. In times of uncertainty, people will save any extra money they receive, not spend it. The stimulus will have a negligible effect on the economy and will only increase government debt."

Based on the principles governing the effectiveness of government spending, which advisor's argument is more likely to be correct in this specific economic context? Justify your reasoning.
