To me, that's a much better narrative to support increasing the number of doctors than "they get paid too much." Instead, this article reads like a con artist who is using slight-of-hand to distract you from the watch he's taking from your pocket. The trick is the doctor's salaries, but the real stealing is happening from the health insurance companies.
The article mentions how many billions of dollars this "problem" impacts the Federal budget. "Billions" - it's a large number in absolute terms, but relative to the problems with our inflated military budget ($850B), it's a pittance.
What I'm trying to get at is this feels like the kind of thing a propaganda outlet would do to give you a false enemy to hate. Even if the premise is grounded in truth (that US doctors are paid twice as much as everywhere else), it just feels like the wrong villain.
