There wouldn't be much actual savings without massive disruption for providers. Right now Medicare and Medicaid are cheaper per patient largely because they pay below cost for the same services. They are subsidized by private insurance. A move to Medicare for all at current reimbursement rates would require drastic budget cuts at every healthcare provider in the country. That may be what's necessary to fix the broken system, but it would involve a lot of pain.
