Final answer:
Organized labor is the most influential political force supporting government programs to aid the disadvantaged, as it focuses on addressing income inequality amid challenges like outsourcing and automation that affect the job market.
Step-by-step explanation:
The organized labor has historically been the most significant political force in support of government programs aimed at assisting the socially and economically disadvantaged. In the context of the United States, the changing economy due to factors such as outsourcing and automation has led to an increase in poverty even among the working population. As a consequence, there has been a growing political movement, backed by organized labor, advocating for social safety nets like Welfare and Social Security.
Organized labor has played a crucial role in representing workers' interests and pushing for measures to address income inequality. This stands in contrast to big corporations or other entities that might have different priorities, such as maintaining corporate strength or competitive pay and benefits. The rise in discussions around income inequality reflects the evolving understanding of larger economic forces at play, such as the impact of globalization and the changing job market's effect on labor.
