According to the Davis-Moore Thesis, what is one of the main justifications for social inequality in society, and how is this thesis commonly critiqued in discussions about social mobility?

The Davis-Moore Thesis argues that social inequality is necessary because it helps motivate people to fill different roles in society. For example, jobs that require more skill or education, like doctors, are often better paid, which encourages people to pursue those careers. However, this idea is often criticized because it overlooks how factors like race, gender, and family background can limit opportunities for some individuals, making it harder for them to move up the social ladder. Critics argue that not everyone has the same chance to succeed, and that inequality can actually harm society by preventing talented individuals from reaching their potential. Thus, while the thesis suggests that inequality serves a purpose, it fails to consider the barriers that many face in achieving success.
