There are lots of reasons to adopt single payer (and personally in my dreams I’d have an NHS- just take the VA and use it as a base and expand), but one I rarely ever hear about is the impact it would have on innovation. I firmly believe that NOTHING could foster more innovation than people not having to worry about health insurance. I personally know at least a dozen people who are stuck in their jobs because they can’t afford to go without health care. People who would probably be better suited to different kinds of work, people who have ideas they would like to bring to fruition, and so on. With our current system of employer provided insurance, we have an artificially inefficient utilization of our greatest strength- people and their individual talents and skills.
