The supply of MDs & DOs has been kept very low compared to our population growth. The US ends up poaching Drs from around the world. But the actual biggest cost in our medical system is the excessive high administration costs, above the Medicare admin level of 3% it's about 27-29% extra with private insurance and the medical billing side. We have about 27% uninsured. The money is there and going single payer would create savings by delaying lag to care, it would increase preventive care and have a lot of second order savings like with liability insurance. The estimates are at least 3/4 of Americans would save money the first year.
