There's medical school graduates that can't get into residency programs. The bottleneck in the US right now is residency slots.
Providers with billions of revenue could easily afford to fund slots. They'd probably even benefit financially from it.
So refurb gave a reason for a bottleneck, and now we need to figure out why providers apparently aren't taking steps that address it.
I don't know enough about how hospitals operate to understand why that's a good/bad idea.
All residency slots naturally go to US medical school graduates.
