That's just silly. You don't know what you don't know. How do people find racial, social, and political consciousnesses? They aren't born with it. Not upper class white people, and not black people either. Something has to perpetuate it, some event that forces you to awaken to all in the world that's shitty and motivate you to do something about it, and, more importantly, change yourself so you don't perpetuate those things.
Blacks can't get away from the various hells of the world, they naturally find that consciousness at a really early age. Whites are insulated from them through a process that, these days, we call privilege.
It's easy to lampoon white people who suddenly find their social consciousness through some picaresque encounter with world-weary minorities, it's a much-mined cultural cliché. But it's the wrong reaction. Worse, it smacks of egotism, perhaps you think that you're one of those white people that aren't affected by privilege.
