I used to think that all chiropractors were hacks and shills and I've even chided Getbiggers who are chiropractors about it but I don't think along those lines anymore. I think the field has its benefits and uses and that it's better to judge on a chiropractor-by-chiropractor basis. Some are actually quite good at what they do while others are complete shit. I guess it depends on their schooling and how qualified they actually are.
That said, I'd venture to say that it's a better job to have than a lot of others out there.
