The United States artificially limits the supply of clinicians through licensing rules, residency restrictions, and accreditation hurdles that restrict how many doctors we train and allow to practice. As a result, the system heavily depends on foreign-trained physicians, especially in underserved areas. Limiting their entry only worsens a shortage caused by domestic policies.
The USA has a disproportionate number of the best medical schools in the world. Harvard, Stanford, Johns Hopkins, UCSF, Yale, and Penn are all ranked in the top 10. And these colleges are well endowed. Just about every state school in the country has a big medical program (NYU, Cal, Michigan, Florida, Ohio State, PSU, UF, UCF, MUSC, etc. Why can't the USA provide enough doctors? Do you realize the number of doctors in the USA has risen by 79% in the past 30 years while population has only grown 26%?
You act like healthcare was abundant and inexpensive in the USA until Trump took office and screwed it up. That's incredibly narrow minded thinking.
