No, there really aren't many Aboriginal people who aren't disadvantaged* in the health care system. If you are Aboriginal, you can count on getting not only poor care in a systemic sense, but poor, rude and oblivious care from the individual health care workers.

ETA: * to be more clear, the vast, vast majority of Aboriginal people are disadvantaged in the health care system, whether they are dark or pale, remote or urban, poor or wealthy and educated or not.
