What underlying factors contribute to the observed disparities in income and wealth distribution among different quintiles in American society?

The differences in income and wealth among various groups in American society, often categorized into five quintiles, can be traced back to several key factors. One major reason is education; people with higher education levels tend to earn more money and have better job opportunities. Additionally, access to resources like quality schools and networking can vary greatly, leading to unequal chances for success. For example, someone from a wealthy family might attend a well-funded school and make connections that help them get a high-paying job, while someone from a lower-income background might not have the same opportunities. These disparities create a cycle where the rich can accumulate more wealth, while those with fewer resources struggle to improve their economic situation.
