Big insurance and their bought and paid for politicians will fight single payer tooth and nail.  If and when public opinion swings far enough to apply enough pressure to make it a reality, we may join the rest of the western world, with coverage for all.  Think about it, the uninsured get little or no preventive care and present in emergency rooms for care, you are paying for that.  Make it a requirement for wellness checks perhaps, catching conditions early is so much better and saves $$$, and improves health for all.  Offer incentives for more to enter the medical field, be smart about immigration and allow skilled health care professionals to work in the USA, improve care in rural areas where it is needed most, stop the slide toward 3rd world life expectancy numbers, improve productivity and lost time for employers, this is not rocket science, keep politics away from health care.
