What is the the result of social stratification according to Davis-Moore?

According to Davis-Moore, social stratification results from a functional necessity in society, where certain positions are more important and require higher levels of skill and training. As a result, there is a natural hierarchy that rewards individuals who occupy these positions with higher levels of power, prestige, and income. This system is believed to motivate individuals to work hard and strive for success in order to attain higher social positions.
