I think you're misunderstanding the whole message behind this scene. What happened in Ramayana has nothing to do with the plight of doctors in India today. That is due to the horrible laws that do not protect the doctors when patients find loopholes in them.
The whole meaning behind Hanuman bringing Sushena to Rama is to teach humanity the true meaning behind being a doctor. No doctor should ever discriminate between two patients, no matter their caste/color/ethnicity, etc. This is actually a very progressive teaching for that era, and one of my favorite lessons from the Ramayana. Sushena was a good doctor, but he believed his loyalty was towards Ravan and Lanka. Even in the Vedas, there is an oath for doctors similar to the Hippocrates oath, in which they vow to treat any and every patient regardless of caste and disease. Sushena forgot that oath and refused to treat Lakshmana, and thus Rama reminded him of his duty as a doctor in gentle terms. Neither Rama nor Hanuman were abusive to him. Hanuman brought Sushena's house along with him, but for Hanuman that is such a small feat, and he replaced the house back once Lakshman was revived (they did show this scene in the show btw...maybe it was edited out later on but it's in my dvds). So it's not like Sushena lost his housing or anything. It's also mentioned in Ramayana that Sushena continued to be the Raj Vaidya even after Vibhishan became King, so his life wasn't affected in any way. Some versions of Ramayana do mention he was imprisoned by Ravan, but isn't there a message behind that also?
After all, doctors are in a risky field just like soldiers/warriors. Sometimes, when one is supporting a good cause, there is a risk of imprisonment when the government (an unjust King) is against the good cause. During those times, isn't it the duty of doctors to treat a patient regardless of the risk? Just like doctors today are treating patients testing positive for Covid-19. There is a risk of those doctors dying themselves, but they are fulfilling the duty they have towards their oath and their very field.
That is the basic message behind this Sanjeevani incident. A doctor who makes an oath to treat a human life must fulfill that oath no matter the risks required. If a doctor cannot do that or does not wish to do that, or if a doctor has his personal biases and refuses to treat a sick patient for any reason, he has no business being in that field. My sister is a medical student and this is something they teach in her school also. They tell the students don't become a doctor because it seems like a lucrative field and you'll make a lot of money. Only become one if you have the guts to do your job even when it's difficult and scary. It's not an easy field, but it's a very valuable one.
