respect isnt base on rankings or what the MD's percieve , its about the relationship you have with your clients.
at the end of the day if you believe you made a difference and you make decent money for your family, why do you care about how the MDs percieve your profession? while it may be necessary to convince MDs of your training to obtain a working relationship, respect is not what you want from them. you want respect from your patients, even if you get those ignorant ones that believe you are a md wannabe, as long as you give them the highest quality care, i dont see why you cant sleep soundly at night
so back to the original question, why shouldnt chiros be respected and given a high ranking if they deserve it? if they are able to make a difference in thier pateints and practice at a high level with respect to thier training, ill tip my hat to the chiro over any self proclaiming and arrogant OD, MD, pharmD anyday
