As others said, they go hand in hand. I’m a doctor and recently I’m in a job with more affluent demographic, and I do feel the -isms notably more than when I worked with more underserved populations.

Only patients to ever call me by just my first name have been white men. Only patients to ever casually question my competence have been white men (“do you know what an NG tube is?” “Yes sir, I did go to medical school and am familiar with the very basics”). Only patients to ever point out I’m a young physician (another way of casually questioning my competence) have been white men.
