Court:
In answer to your first question, I would say that it is not that other professions do not get respect, it is more that they do not command the same respect as being a physician. There is a big difference.
In answer to your second question, the answer is a resounding "No". To say that non-physician health care providers are all "MD-Wannabes" is an obvious inaccurate blanket-statement and I think you know that as well as I. Having said that, those who cannot get into medical school will invariably find another role in medicine and will tend to seek positions that are as similar to being a physician as possible. For this reason, a high majority of those who cannot get into medical school may seek professions such as PA, NP, CRNA, Podiatry, etc. That is not to say, however, that most who are PAs, NPs, CRNAs, Podiatrists, etc. are people who could not get into medical school. That is just not true.
I don't think that what you are reading on this website should cause you to be concerned that non-physician healthcare providers cannot see the importance of their respective field, because I just don't think that is true. One certainly cannot come to that conclusion from this website. You must consider the fact that the amount of people who frequent this forum represents less than a fraction of the overall healthcare provider force in this country. For this reason, take everything you read here with a grain of salt. Form your opinions based on real-life interactions with human-beings, not website forums. You will likely have a better experience.
Good luck.
