Do you mean we want to erode doctor/nurse pay because that's what's causing high healthcare costs?
It's been awhile since I worked in healthcare but I don't think primary care provider pay is high on the list of most impactful cost cutting improvements
My experience is that doctors are not the primary bottleneck but the system is rather inefficient in many other aspects.
I think if you add more people to a bad system you tend to make things worse. Better to fix the process rather than throw more (poorly managed) resources at it
