The biggest economic threat to political stability in South America

is income inequality. The region has some of the highest levels of income inequality in the world, with a small wealthy elite controlling a majority of the wealth. This disparity can lead to social unrest, protests, and ultimately political instability as marginalized groups demand more equitable distribution of resources and opportunities. Additionally, economic downturns, corruption, and lack of access to basic services and education can further exacerbate these tensions. Addressing income inequality and promoting inclusive economic growth are crucial for maintaining political stability in South America.
