Most of us have been veiled. We have learned to think in the way our culture has taught us to think. I doubt that I need to cite evidence for this claim. The function of culture is to indoctrinate those within the culture into the dominant way of thinking. The dominant way of thinking is unsurprisingly controlled by those who benefit most from the dominant way of thinking. So in a way, I agree with my friend: who wants to read memoirs from those who have been brainwashed?
I don't know where to go from here. Who has and hasn't been brainwashed--and who's washing our brains? On the surface, it seems as if people who read and have been perhaps super-educated are those who might have evaded the washing machine. A book by Jeff Schmidt, Disciplined Minds, challenges this assumption of educational-privilege. Schmidt, a physicist, argues that the more degrees you have obtained, the more you have been washed. He makes a good case. The more degrees we obtain, the more we benefit from the existing order--and consequently, reinforcing that order to maintain our privilege.
These are random thoughts. I don't expect anyone to take them seriously. I think, however, that if we find a way to encourage and listen to the voices of the disenfranchised, we might move forward rather than running in place.
