Here's a fact: Half of all professional school graduates are in the bottom half of their class.
Here's an opinion: The bottom half are still better than the top half of chiropractors.
Here's another fact (well, possible fact): More than 251,000 deaths in America are due to medical error. By medical, I mean hospital/doctor/nurse. (I found that on the internet, so it must be true.) Of course, a closer reading of the data suggests that that number is inflated, but, still, the number is high (that's more like an assessment than a fact or opinion). https://www.sciencebasedmedicine.org/are-medical-errors-really-the-third-most-common-cause-of-death-in-the-u-s/
I will venture a guess that chiropractors and other alternative providers don't account for nearly that number of deaths. So the question is do they do any good. My experience is that they do. And I will argue that this is as much because of the work they do as well as the time they spend with you - sometimes it's more important that someone just spend time caring for and caring about you. What they do is almost secondary. And the alternative provides do that. Yes, sometimes these providers cross the line, as do doctors. And, yes, sometimes (often) you have to turn a critical eye to some of the things they do/recommend. For example, many (most?) chiropractors have got into various supplements, cleanses, and more. Clearly another revenue stream for them. So maybe that's an occasion to think twice. But, again, sometimes you have to exercise the same judgments with respect to your conventional medical professionals.
