Why didnt Joe Buck just get Ratso a Doctor or take him to the hospital?
Thats one part that always bothers me upon rewatching this great movie, Joe Buck goes from hating Ratso Rizzo early on because he was ripped off by him and taken to the cleaners when Ratso stole twenty dollars off of him and ditched him with Mr. O'Daniel but Ratso takes Joe to his apartment and makes it up to Joe by teaching him how to survive and getting him his first customer Shirley.
When Joe Buck returns from his first successful Hustler score with Shirley he is told by Ratso that Ratso does not think that he can walk anymore because hes been falling down a lot and is scared, he needs to lay down and feels hot and Joe goes to leave to get a doctor for Ratso but he refuses to see a doctor and Joe Buck settles for doing a Hustler job to get the money to bring Ratso to Florida as quick as he can which he does after he supposedly kills Townie and robs him of all his money.
But the main question is why doesnt Joe Buck just leave the apartment and call 911 and bring an ambulance and just have Ratso taken to a hospital where he could be treated in an emergency room and discharged after a few days?
Hospitals have to treat anyone that comes to them under the law, homeless people like Ratso Rizzo have no money and cannot pay for treatment but cannot be denied treatment under the law at all either, likely Ratso would have been given some shots and antibiotics and some food to help him recover and then get released after that, hospitals cannot hold people against their will and Ratso would have been fine, the downside is that the Ambulance crew would have contacted the police and landlord and informed them about Joe and Ratso squatting in that building and they would probably lose their home after that.
But it would have saved Ratso's life, Joe could easily rob Townie and score with Shirleys friends while Ratso was in the hospital, find out when he was supposed to be released and take him to the bus stop to go to Miami right after he got released, This way Ratso would have survived the bus ride and lived in Miami with Joe as his caretaker.
Joe wouldnt have lost his best friend if he had just called an ambulance and had Ratso removed and taken to the hospital, Ratso would get over his anger at being taken after he was treated and released anyway, never understood why Joe thought that bringing him to Florida would improve his condition.
Hospitals treat people for tuberculosis and pnuemonia all the time, Ratso would have probably recovered and not had to pay for his treatment, then left New York with Joe as planned.
