I would guess the real question is not the percentage of independent doctors, but the number of total doctors, before and after.
Independent doctors, like Walmarts, can be found adjacent to Vermont’s long borders with New York and New Hampshire.
Not entirely. Once herded into big organizations like hospitals, medical professionals are easier to regulate and control, and less likely to introduce disruptive commercial innovations that threaten government's powers over health care, and hence over a once-free people.
