It's no wonder doctors don't like this. People can opt to not have health insurance or for Seniors Medicare Part B and go to a less expensive clinic with a doctor who hasn't finished their residency but has recently completed, most current, medical knowledge.
Med students when they graduate have done only 2 months in each specialty plus some electives. The real training is done during residency.
The residency is where you actually learn to practice medicine. It’s not like 1950.
