The problem in the US is far bigger than the cost of medical education.

The US doesn't have single payer healthcare. For every medical professional actually helping a patient, there's a legion of bureaucrats (administrators, insurers, accountants and lawyers, along with all their support staff) spread over a huge network of businesses adding their cut. Go to the ER and you'll be getting bills for it 2 years later. This massive overhead needs to go away to enable price transparency and reasonable costs.
