Modern stratification systems are considered to be:

Modern stratification systems are characterized as complex and multifaceted due to the various dimensions through which social inequality is assessed and experienced. Stratification does not rely solely on one single factor, such as wealth; instead, it incorporates a range of elements including race, gender, education, occupation, and social capital. This complexity reflects the interplay of different social categories and how they impact individuals' life chances and access to resources.

Understanding stratification as a multifaceted system allows for a more nuanced view of how societies organize themselves and how power and status are distributed. For instance, two people may have the same income level, yet their social standing could differ significantly based on their educational background or racial identity. This highlights the importance of recognizing how various forms of inequality intersect and create distinct social hierarchies.

In contrast, the other options simplify these dynamics. Viewing stratification as simple and one-dimensional ignores the complexity of social hierarchies and the ways they can change over time. Claiming that stratification is non-existent in today's society dismisses the evident social inequalities that persist globally. Lastly, stating that stratification is strictly based on wealth fails to acknowledge other critical factors that influence status and opportunity in contemporary societies.
