--- That's hitting it on the head. Even today my Dad's generation brings that up in conversations. I think both of your other points are pretty much accurate too. Don't forget that Jewish doctors are a pretty big subset too and they ARE FURIOUS with Obama. Some are clients and the conversations I have with them are almost vicious in their disgust.
Though the percentage of doctors that are Jewish is several times the percentage of the general population that is, and many Jewish doctors may be furious over Obamacare, the unfortunate facts remain that Jewish doctors as a group have never had much political clout within the Jewish community, and that doctors in general have been treated with contempt by the ruling left-dominated political class for many years because the profession as a whole is thought of as being politically impotent (except for the traitorous AMA, but that's another story).
If the medical profession was treated with any kind of respect by the leftist political class - anywhere close to the way the trial lawyers are - ObamaCare would never have come close to happening.
