I am white. Until recently, I never gave serious thought about white privilege. Sometimes I speed on the highway, past a cop, and I do not get pulled over. I have gotten many warnings, instead of tickets.
In school, I always got the benefit of the doubt, that I was capable of doing the work. I never had much trouble with job interviews. In court, I am treated with respect,by lawyers, judges, and litigants.
We were poor when I was growing up, but my sister and I always felt that we could succeed. She is a mathematical genius. We were put in the accelerated classes for the smart kids. We knew we were going to college, even though we needed scholarships and financial aid to get through.
White men had it even easier than we did. They looked for part-time jobs in the "men's" section of the want-ads and got paid more. They were, and generally still are, the bosses. We worked hard at our typing jobs working through college and did okay.
I know of Black executives and politicians who routinely are subject to traffic stops. Most bosses are white men, not people of color. We don't hear the "n" word like I heard it as a kid, but implicit bias is a real thing. The people with the most power are still predominantly white and predominantly men.
I do not know when or if society will change. Change terrifies those with power. People don't willingly give up power, especially when they refuse to acknowledge that they hold the power. Just look at Fox News. A bastion of white, male privilege. Roger Ailes was bought out for $40,000,000. Let's see what happens to Bill O'Reilly. I bet neither Ailes nor O'Reilly believes in white privilege, while they continue to profit from despicable behavior.
