Certainly, in America, doctors seem happy enough to prescribe painkillers to people who can’t afford actual treatment. I mean, for the medical-industrial-insurance complex, being able to charge people/increase their premiums, year after year, has to be a steady revenue stream. Chiropracty could fulfil the same niche, I guess.
Over here, in the UK, it is apparently very difficult to get Chiropractic treatment on the NHS; so “patients” are generally going to have to pay to get private treatment.
