Final answer:
Kingsley Davis and Wilbert Moore argue that societal positions must be filled by individuals with the appropriate talents and abilities, as presented in the Davis-Moore thesis, which posits that social stratification is essential for rewarding and motivating the most capable individuals for high-value tasks.
Step-by-step explanation:
Sociologists Kingsley Davis and Wilbert Moore believe that positions in society must be distributed, and these positions must be filled by people with the appropriate talents and abilities. According to the Davis-Moore thesis published in 1945, social stratification is based on the inherently unequal value of different work. The thesis suggests that certain tasks in society are more valuable than others and, therefore, the individuals who fill these positions must be rewarded more than others. This stratification is seen as a social necessity to ensure that highly skilled positions are filled by the most capable individuals, providing a financial motivation for people to undergo the required education and training.
