Well, I do agree with you that we need more doctors. But few doctors work four-day weeks. Just the opposite -- which is exactly what you'd expect of any kind of worker who was in short supply. Most doctors put in brutally long hours, often working for months on end without a day off. Twelve hour days are not uncommon either. Also, very few doctors make anything like $400,000/yr.
This happened less than two months ago. My mother broke her hip and was too weak to be cared for at home. A doctor and physicians assitant came to her room unsolicited to talk to her about going to their facilty. Their faciltiy will only take a patient if they can dress themselves. She could not and it was known by her doctors, nurses, etc. He talked to her all of 2 minutes (the PA said nothing and stood in the doorway) and told her that all beds at his facility were full anyway. I was there. His bill was $175.00. How much money did he steal that day, probably every day, walking the hospital floors "consulting"?
Many years ago a lady told me she wasn't afraid of dying and going to hell because she was sure there would be more than enough doctors and lawyers to take care of her needs just like here.
