Many people are not aware that about 25% of each health care dollar goes to administrative expenses in the USA (mostly red tape and profit for private insurers). That compares with about 5-10% in Canada, France, England, Germany etc. So there's a lot of room for improving care by paying nurses and doctors instead of administrative personnel. We have the most expensive and most wasteful system in the history of the world. Medicare is comparable to most national systems in having a very low overhead, so Medicare for all would actually enable spending more on health care and less on the erratic and inefficient system we now have. It doesn't even have to be government run, just more highly regulated and cutting out the profit motive, which serves no one except the insurance company executives who have boat payments due

.
Even our not for profits, like Blue Cross/Blue Shield are a financial drag on the system. Locally, we have dozens of executives who are paid more than I am (and I am an ancient and thus well paid salaried physician) and many who earn more than any of our neurosurgeons, orthopedic surgeons, etc. who are the highest paid physicians. This isn't sour grapes, it's a simple statement that there is no reason for paying hundreds or thousands of executive vice presidents more than our highest paid physicians and nurses for doing essentially nothing to improve healthcare. This is capitalism at its worst.
