Final answer:
Social stratification is the system that has influenced voting practices, leading to lower voting rates among individuals with lower socioeconomic status.
Step-by-step explanation:
The concept that has influenced voting practices, where lower-educated, lower-paid workers have a lower voting rate compared to individuals with higher socioeconomic status, is social stratification. Social stratification refers to the hierarchical organization of people into different social categories, such as wealth, income, education, and power, which can lead to unequal access to resources, including political power. This stratification creates a cycle where those with more resources continue to maintain and extend their power and influence, affecting various socioeconomic issues, including voting behavior.
