See, my plan is to help fix the health disparies of marginalized groups that have been mistreated by those in the healthcare system. There is no evidence of white people or rich people being treated poorly in this context, so there is no problem, so there would be no reason to provide training. If historically white people were given fatal diseases then not treated for experimentation purposes without consent, their cells taken and sold without seeing a dime, if educated white women had significantly worse rates of infant mortality than black women with only high school educations, then yeah it probably would be a good idea - but that's not the case.
Addressing issues like these is way beyond the scope of a med school course or GME on empathy. Issues like infant mortality are huge issues that no doubt need to be fixed, but still they have nothing to do with physician empathy. A girl with only high school education and no access to healthcare is going to have a bad outcome regardless of her race. Yeah, the data shows that this outcomes are worse with black girls compared to white girls, but that's more about their access to care than their race. Take a black teen girl in an affluent neighborhood and a homeless white teen girl. The black girl is going to have a healthier baby. The issue here is a societal one, not one that the average physician is going to tackle from his/her office.
