Review Questions

• How does income inequality affect social cohesion and political stability within different economic systems?
  • Income inequality can significantly affect social cohesion by creating divisions between different income groups. In systems with high income disparities, social mobility may decrease, leading to resentment among lower-income individuals who feel excluded from opportunities. This resentment can translate into political instability as marginalized groups may engage in protests or support radical movements aiming for change. Thus, addressing income inequality is crucial for maintaining social harmony and political order.
• Evaluate how different political-economic systems respond to income inequality and what policies are commonly implemented to mitigate it.
  • Different political-economic systems have varied approaches to addressing income inequality. In social democracies, redistributive policies such as progressive taxation, social welfare programs, and minimum wage laws are commonly enacted to reduce disparities. On the other hand, laissez-faire economies may rely more on market forces to determine income distribution, often resulting in higher levels of inequality. Understanding these responses helps highlight how governance shapes economic outcomes related to income distribution.
• Analyze the long-term consequences of sustained income inequality on a nation's economy and its political landscape.
  • Sustained income inequality can lead to long-term detrimental effects on both a nation's economy and its political landscape. Economically, persistent disparities can result in reduced overall growth due to lower consumption levels from the poor and diminished investments in education and health. Politically, high income inequality may foster polarization and undermine democratic processes, as wealthier individuals gain disproportionate influence over political decision-making. This cycle can create a feedback loop that perpetuates inequality and destabilizes the societal structure over time.
