For example, the supposed inferior medical treatment of blacks.  Nope, it's the facilities, not race.  You're not going to get as good care at an underfunded and overworked facility, the supposed racism is because those facilities are more likely to be in the inner cities (a lot of uninsured patients and a lot who have medicaid.)
		
		
	 
Umm... no, even when socioeconomic and hospital performance factors are considered, there remains a difference in treatment.  About a year ago, I don't recall exactly when, a subsidiary of United got sued because they built a predictive algorithm for use in triage and prioritizing patients, identifying those who need the most intervention and the most attention.  The algorithm produced biased results, because the data going into it was biased.
At the end of the day, even controlling for everything else, black people (especially men) are assumed to be healthier, tougher, and more resistant to pain than white people are.  As a result, they get less treatment for the same severity of illnesses.
On a similar note, women also get less treatment, although the driving mechanism is different.  Women are generally assumed to overstate and exaggerate their symptoms... and there's a tendency for doctors (even if those doctors happen to be women) to discount women's complaints.
