Privilege is a relative thing. No, a white boy born in a trailer is not going to have the same privileges as the Obama girls. Where it is real is in how much harder it is for a black girl born in the same park. OWGs (and I am one) do get it easier ALL OTHER THINGS BEING EQUAL. We do not face a history (only finally dealt with in the Anglophone world in the 1990s and currently showing a disturbing resurgence) of legally entrenched discrimination on the basis of our sex. We do not face a history (only finally dealt with in the Anglophone world in the 1980s and currently showing a disturbing resurgence) of legally entrenched discrimination on the basis of our race. They're the two biggies followed by discrimination on gender, and sexual preference. All these things produced systemic biases that favour OWGs. We don't think about them because they don't hinder us. Quite the opposite. Where the diversity movement is shafting everyone is that it is shutting down (as you say) discussion of class. Progressives are scrabbling for position at the bottom of the barrel rather than smashing their way out.

As gently as I can. You want diversity to be about you, a white dude. So you believe your chances in life were hindered by being a white dude, for real?

You might find this article worth reading. He suggests that diversity makes it easier to avoid talking about class. [prospect.org]

You know, I think it's a fair but delicate question. Be careful asking it, because everyone is used to some pretty awful racist feelings being concealed in this sort of inquiry and will respond in a way that is meant to say that in no uncertain terms, being an old white guy has advantages you can't even see because it's just the water you swim in. But I'm going to assume that your question is well-intended and that you are coming from a good place: White-Trash Americans ARE disadvantaged. With no example of success, no help getting started in life, no connections, no ability to mix credibly with people who in other societies would be called your "betters", you have an uphill climb. Makes it hard when you get lumped into the Oppressors Group. You get stereotyped if you don't try to rise above and stereotyped if you do. My advice? Use this experience to understand how other stereotyped groups must feel. Live like you can see the humanity in everyone, including the privileged, by the way, but don't be too in awe of them. They get stereotyped too, mostly as assholes, or idealized as smarter, better looking and more deserving than the rest of us. Then remember: we all carry some baggage from history. People have been pushing others around, conquering, fleeing their homes, finding new homes, waging wars and winning and losing since before history. People's memories are long, but not long enough to understand that history has made winners and losers of just about everyone at some point. We are all the same. But the function of historic memory is, among other things, identity. Start by knowing that historic resentment had a beginning. Refuse to participate in the contest over who has the biggest right to a grievance. If your own life is a struggle, identify with all who struggle everywhere, not just those who look like you. Compassion for others is always a good place to start.
