Why doctors lawyers and Janitors aren't all paid the same?

Doctors, lawyers, and janitors aren't all paid the same due to differences in education, training, and the nature of their work. Doctors and lawyers typically require extensive education and specialized training, leading to higher salaries that reflect the complexity and responsibility of their roles. In contrast, janitorial work, while essential, generally requires less formal education and training, resulting in lower wages. Additionally, market demand and the economic value placed on different professions further contribute to these salary disparities.
