In Canada the opposite is true.
It's impossible for any but the wealthy to sue a doctor, dentist, surgeon, or psychiatrist for malpractice. So doctors play fast and loose with the vulnerable. Their attitude towards low income folks is they should be grateful for whatever free service they're given, including unnecessary surgeries, useless prescriptions, and other unnecessary but billable procedures.
   If we made the legal system actually democratic, affordable for all, the medical system would improve significantly for fear of malpractice litigation.
