Eeek! Hope no one thinks I'll be an arsehole cardiothoracic surgeon ten or more years from now! I've heard from many, many people, not just the previous poster, on how rude and cocky a lot of surgeons are. Even my great uncle, a retired general surgeon himself, admits and agrees with that!
Still, I can see the point of each argument presented, and although I can't really pass judgement on any of them, mightn't it be that all of them have a grain of truth? Whenever has any single social problem been reducable to a single cause? One can probably very easily find a doctor who is motivated purely by money, but one can also find a doctor motivated purely by the desire to save lives, and it is certain there are doctors out there somewhere who just want it for the power and prestige.
And then there are those who do not fall into such extremes. Myself, I think I'm motivated by all three. Isn't it the American Dream to try to climb as high as you can on the money/power ladder? Aside from that, who doesn't want to live comfortably, who doesn't want their kids to live comfortably? As for pride: I will take great pride in the amount of schooling I will have successfully (I hope!) struggled through, but I doubt I'll let that govern my attitude towards "underlings:" I'm a CNA right now and know what it's like to squirm under higher authority.
Lastly... even if one doesn't want to help people live, one really doesn't have much of a choice! It's the profession: doctors don't stay doctors long if they don't do what they are called to do.
Just my four cents, well, okay, maybe that was a dollar's worth, but anyhow!
