I've read about that before. I personally am of the belief that Medicare funding for residency slots should be eliminated over time. Also freely allow the opening and expansion of medical schools and teaching hospitals. Over time things should settle into a comfortable equilibrium of enough doctors making decent wages for everyone to be treated at a reasonable cost.
But maybe that's a free market fantasy. Who knows.
Or the alternative. Government-owned everything healthcare - facilities, hospitals, med schools, doctor practices. Doctors only work for the government.
The current system is neither here nor there and is designed for maximum profit.
