Final answer:
Income inequality in the United States has become more pronounced since the 1980s due to economic restructuring and supply-side economics, contributing to social and political unrest. The Gilded Age-like wealth disparity and the U.S.’ historical relationship with oil-rich nations such as Saudi Arabia have influenced U.S. prosperity and international dynamics.
Step-by-step explanation:
America's shift from a manufacturing-based economy to one that embraces supply-side economics has increased income inequality since the 1980s. This economic transformation saw greater economic growth, but the gains were disproportionately distributed, enriching the wealthiest Americans and leaving the average citizen feeling poorer. These economic conditions have contributed to a range of societal issues, including health outcomes, psychological well-being, and a resurgence in the cultural and economic divisions reminiscent of the Gilded Age.
In the past, the United States leveraged its position as a world leader in oil exports to establish its prosperity. However, the more recent economic restructuring and tax reforms have reshaped the economic landscape. While the top 1% now possess immense wealth, much of the population has faced a stagnation or decline in their economic conditions, leading to both political and social unrest, and fueling movements such as the 'Trump movement'.
These conditions are compounded by pressing international relations, such as the complex dynamics with Saudi Arabia. Since the discovery of oil in 1933, U.S. companies have been involved there, contributing to America's wealth but also to the contentious relationships rooted in differing cultural and political ideologies.
