Not joking or trying to insult, is "very right-wing, bigoted household" a euphemism for neo-nazi parents? I'm asking because the logical conclusion of what you were saying is that the natural state of white people is to dominate the world, because we are on average richer and more powerful than people with colored skin. If that's the sort of **** you grew up with I can see why you'd have a hard time breaking yourself of it.
Tumblr feminists and social justice folks are incredibly damaging to the discourse (I suspect that most of them are trolling) but buried deep beneath everything there is a good point:
Your successes are built upon the accomplishments of those who came before you. This is a quasi-natural condition: if your mother is healthier, and if you're fed better as a child, more energy can go to developing brain tissue and you end up smarter. What we have goes far beyond that, though. Highly-educated parents produce better educational opportunities for their children, even if it's just keeping old university textbooks on the bookshelf. Living in a nice house, in a rich town, means you'll go to a better school by default because public schools are funded by property taxes. Wealthy, stable parents inure you to risk; you can experiment with education and finance from a stable position, gaining more experience than others your age. You're white, so it's fractionally easier to find a job and you get a fractionally higher yearly raise, and you're male, so it's fractionally easier to find a job and you get a fractionally higher yearly raise. All of this also means you have more money, so you can save for your retirement at a younger age. Money compounds. Intelligence compounds. Experience compounds. Job performance compounds. And at the end of it, you did little or nothing to earn any of the advantages you have. This is what "privilege" means.
