I read a good deal of MarketWatch material, but that is some questionable journalism right there.
"And by most projections, it’s only going to get worse — the U.S. could lose as many as 1 million doctors by 2025, according to a Association of American Medical Colleges report."
The link in that statement does not say that. (I've included it here below.) All it says is demand will not be fulfilled based on our aging trends.

What it says is what we have known for sometime now about the strain on the current process to become a doctor and then the business model of a doctor's practice. We already know there is a shortage of doctors in the area of primary care and several specialty disciplines, and it is well covered material that the debt one needs to acquire just to become a doctor is absurd. Another factor is ACA greatly accelerated the mechanism between primary care doctors and Insurance Companies putting downward pressure on the fees for a doctor's practice. Basically, a demand issue is artificially coupled with a business model issue.
"The primary-care gap is particularly acute in about one-third of states, which have only half or less of their primary-care needs being met."
"We pay for procedures, drugs and expensive tests, but we don’t pay doctors to think and care and manage patient health-care problems."
With baby-boomers going into retirement, something like 12000 per day retire, will place upward strain on the system where we seemingly take the primary care physician and pay them less but expect them to care for more.
The issue at hand now is finding more doctors to get through a costly 7-8 year process, including internship, to then convince them go to into the lowest paid area of medicine... join (or start) a family practice as a primary care doctor. The government screwed around in this so much that everyone else got something but the very group we need to ensure we get more of.
On the lighter-side... Healthcare Insurance companies are showing record profits, and their CEOs are making a fortune. Check Anthem.
