If I write somebody a letter, it gets taken seriously. The guy opening it shows it to his manager. His manager shows it to her manager. Maybe I still don’t get what I want—but I get treated well and taken seriously. My letters—even the angry ones—are unfailingly polite. I don’t need to be angry to get somebody’s attention. I just need to sign the letter “Attorney at Law.”
Being a white guy has the same relative effect. It takes negligble effort to be treated well and taken seriously.
