With a median annual wage in the six figures, it's not surprising medicine ranks behind only law as the most popular doctoral degree. However, not all medical degrees are great investments. Depending on the specialization, salaries for doctors can vary by hundreds of thousands of dollars. Despite intense competition for spots in prestigious schools and residencies, there is a critical shortage of primary care physicians. Considering the massive debt many new doctors are left with, it's not surprising careers in primary health tend to be overshadowed by higher paying specializations.
