Yes, there will be a doctor shortage because many of them who are over 50 y.o. will retire before they allow non-physicians to make decisions about what tests they can do and what care they can provide.
However, those 30 million supposedly new individuals who don’t have insurance are already getting health care. It’s not like there are 30 million new folks who will drop out of the sky. Go to any emergency room, go to any clinic, you’ll find them there. Ask any doc what percentage of his patients pay nothing.
There will be nothing left for people with real health problems
or the working classes who won't have the time to wait two days in line
when their families need money for food.
I see a crisis on par with a need for martial law.
