Leiflet I agree with you completely. In the hospital where I work, lots of different people wear white coats, from lab workers to PAs to nurse managers. I really don't think many of them went through the thought process of "Maybe if I wear this coat, everyone will think I'm a doctor, which is way more prestigious, and then I can give out medical advice hahaha (wicked laugh)". Actually, most of us are just given a set of options for our uniforms, which sometimes include white lab coats. All the doctors wear black MD badges (and many don't wear white coats at all), and although the patients may not be clued into that yet, I'd like to think that anyone that is caring for a patient and is wrongly addressed as doctor is not running away with the assumption.
Also, wearing coats when you're around patients all day can get kinda gross (I guess there's evidence to back this up), you have to admit that at least WHITE coats are better than say, black, if you're going to wear a coat anyways (which many hospital workers do since its so darn cold in there). I kind of see it as, you're going to wear a coat that will get dirty, but if you wear a white coat, you will more likely keep on top of cleaning it since it will be really obvious if you don't-maybe that's why administration or whoever is encouraging white coats for everyone. Either way, as long as people aren't taking advantage of others' ignorance/assumptions with their white coat wearing, I couldn't care less who has one on.
I also think that picturing the whole hierarchy of the hospital from doctors down, as described a lot here, is a little bit egotistical, whether or not it's true. Doctors may write orders and be "in charge" of others, but that doesn't make them better than other people in the hospital. It seems like a lot of this debate is based on the perception that doctors are the best and everyone is trying to emulate them, which I really don't think is true in most cases. Yeah, traditionally white coats have been for doctors, but this is not the military (for most of us). Saying a nurse or PA has not earned a white coat like a doctor has is a little like saying everyone's goal should be an MD and those who don't have it have just failed in life. I'm not trying to offend anyone, and I obviously don't have the perspective of those who have "earned" their coats, but I'm just trying to give the perspective of that janitor who is given the option of white coat or no coat. I really don't think he or she is trying to take something away from what it means to be a doctor. If our culture does dictate that wearing a white coat yields respect and prestige, then having people copy it, if it really is copying even, should be seen as flattery, not just fuel for the ego and condescension fire.
