My humble opinion is that since the chance to implement a socialized healthcare is slim, they are doing this "through the back door " or backward. By having this bunch of nurses acting as doctors, you will have more supply than demand and the goverment finally can have a system where the cost of healthcare will be lower since they certainly will not pay the nurse the same fee they will pay a doctor and the insurance companies will encourage their clients to go a see a doctor nurse instead. In this whole mess, the affected ones are going to be us, the medical students or current doctors.
