If doctors took an oath to help out anybody and do the best of their abilities, then they would be doing pro bono work 24/7. Some do, I salute those people. Some doctors donate free time to the Red Cross and disaster relief. With their own practice, they do the best of their ability because they like their job and/or they like the pay. They fulfill all of their duties as a physician so that they can keep their jobs and because they like to help out people, I agree. But, at the end of the day, they want to have a good life and give a good life to their family. As with anything, if you take away competition, quality and efficiency will decrease. These doctors will continue to do their jobs but as I said, there is no reason for them to stay an extra 4 hours if they don't get paid to do it. Not saying that some will to, as you said, fulfill their vow, but not every doctor is like that.
There will be more people going to see the doctors because they now have access to it. Volume will increase.
When I broke my thumb and just recently when I got a root canal, my doctor and my dentist gave me their phone number to call if things get out of hand. My family physician even called everyday to check up on my brother when he had his tonsils removed. They are friendly and they go above their obligations because they want to keep their business and their job. It is a service industry. The people at the USPS, the DMV, etc...are in all of my experiences, zombies that are just doing their job. They have no incentives to do a stellar job. Now I have never been to a country where Universal healthcare is used and myself have used it so I can't say for certain what it will or won't be like but I can make simple observations and deduce what the situation might be like from what happens here and form an opinion thusly.
I never said that they would let people suffer. I made an example of being overly friendly, having Holiday cards posted throughout their waiting room, actually forming a relationship with the patient, etc...I never said that they would put a bandage over a gaping wound and send you off. It will lose its personal touch is all I am saying.
As per this thread, do doctors outside of the US do that? Are they overly friendly, have tons of Christmas cards, know your name without looking at a chart, smile and make jokes with you, actually engage in conversation to learn things abotu you, etc...? Or, are they like the ER's here and just trying to get everyone in and out.
