.....47 million or 30 million, it makes no difference....there’s still not enough doctors/nurses to handle the increased case load.
Do you mean there are 30 million Americans now who don't receive medical care? I don't think so. We don't have bodies lying around in the streets because of lack of medical care. In fact, in most states, those with no insurance go to the same doctors and get the same care as anyone else.
The problem is the inefficient way we handle care for the uninsured, not that the uninsured do not get medical care.
There might be additional need for medical personnel if people who are not insured now make more visits to a doctor for preventative medicine, but even this might reduce their doctor visits in the future.
