Where will the additional doctors and MRI machines come from if more folks had access to healthcare? If all the uninsured in my state suddenly had the same access to health care as I did, there would be 700,000 additional people who need primary care physicians, OBGYNs, psychiatrists, and so on. I think it would be a net good, but I would absolutely expect that the wait time for treatment would go up. You can't just snap doctors into existence. (I mean that) Healthcare in the US isn't fair for anyone.
