Are general practitioners or specialists predominant in the US healthcare system? Are general practitioners or specialists predominant in the overall healthcare industry?

The U.S. healthcare system is a combination of general practitioners and specialists. It's hard to say who dominates. For example, the average working class person has a family doctor, and the average patient goes to the family doctor first, and if the family doctor feels that he can't treat the patient, he will refer the patient to a specialist, and the specialists in the United States are really very good at what they do. This is the most common form of medical treatment in the United States now. This kind of medical system in the United States is also not very good, it is very troublesome to see a doctor, if you have an emergency, you can often only see the emergency room, but the emergency room is to deal with those who are dying, can not take care of this kind of general patients. General practice plus specialization is an inevitable trend, and you can't have one without the other.
